Conventional radiographs are much less sensitive compared to MR regarding the detection of early osteonecrosis. The cardiothoracic ratio is a guide to determining cardiac enlargement. Cerebral arteriography not only allows aneurysm identification, but also provides other critical preoperative information such as aneurysm orientation, presence of vasospasm, location of adjacent vessels, and collateral intracranial circulation. B. left upper lobe collapse. Reston, Va: American College of Radiology; 2008:23-37. 3rd ed. On a radiograph, areas that are more white than the surrounding area are said to be more opaque. These subpleural reticular markings represent interstitial pulmonary fibrosis, which almost certainly represents asbestosis (Figure 4-48 B). The limitations of the barium enema include diagnosis of small colonic polyps and mild inflammatory bowel disease, especially with use of the single-contrast technique. In general, the value of nuclear imaging in the urinary tract is severalfold: functional information related to the quantifiable collected Figure 9-13. A malpositioned central venous catheter may result in inaccurate CVP measurement, thrombosis, catheter knotting, and infusion of substances into the mediastinum or pleura. Less common signs are a circumscribed mass, asymmetric density, and architectural distortion alone. Normal myocardial stress/rest study. The PA view of the chest is usually obtained as part of an acute abdominal series because an abnormality in the chest may have symptoms referred to the abdomen. 3-17. C. degenerative disk disease at C5-6 and C6-7. A 23-year-old woman was involved in a motor vehicle accident. Also, because of these practical considerations, routine mammography is not performed in markedly debilitated patients.

Nephrolithiasis is the most common cause of calcification within the kidneys. In this case, peripancreatic inflammatory changes and a high-density collection are seen adjacent to the pancreatic head, representing a collection of blood created by hemorrhagic pancreatitis (B is the correct answer to Question 11-16). Pearls and pitfalls in the diagnosis of ureterolithiasis by unenhanced helical CT. RadioGraphics. However, subluxation refers to partial loss of congruity between the articulating ends of bones, whereas dislocation denotes complete loss of congruity. Although there are many causes of adrenal masses, the most common include benign adenomas, metastatic disease, adrenal carcinoma, and myelolipomas. The lateral view of the wrist (Figure 7-17 B) shows that the radius, lunate, and capitate are in an almost straight line. In this case, the liver has an irregularly linear lesion in its central aspect, representing a liver laceration (B is the correct answer to Question 11-9). Velocity of flow is denoted along left edge of tracing in cm/s. The disks (arrowheads), because of their water content (when normal), appear higher in signal intensity when compared with the T1-weighted image. basic radiology second edition lange clinical medicine Oct 25, 2020 Posted By Gilbert Patten Library TEXT ID 954f337a Online PDF Ebook Epub Library thomas l pope david j ott a well illustrated systems based primer on learning radiologic imaging 4 star doodys review basic radiology second edition lange … In both methods, large and small compression images of all segments of the colon are obtained. A variety of barium products are available commercially, and many are formulated for specific examinations depending on their density and viscosity. Case 9-4. The gallbladder appears as an anechoic pear-shaped structure along the inferior aspect of the liver (Figure 11-2). This recommendation is of particular importance in connection with new or infrequently used drugs. See Urothelial cell carcinoma Transrectal ultrasound, 9 Tumors bladder tumor, 253 bone, 159, 170, 176, 381 brain, 338 pancreas, 320–323 spinal cord, 381 U Ultrasonography (US), 7, 21 applications of, 8 ascites, 228 brain, 334–335 breast, 134 chest, 70, 77 diverse applications of, 9 Doppler ultrasound, 8–9 gallbladder, 215, 216 gastrointestinal tract, 256 joints imaging, 184 limitations of, 8 portal venous gas, 232 sound waves, use of, 7–8, 21 ureteral jet image, 240 urinary tract, 239–240, 243 Unipolar pacemakers, 41 Upper abdominal calcifications, 214–217 Upper gastrointestinal bleeding, 269–273 Ureteral calculi, 218 Urinary calculi, 213, 215 Urinary tract, 233 abdominal radiography, 233–234 angiography, 242 clinical exercises and case examples. In the interval, a small spiculated mass has enlarged so as to become more apparent (arrow) (B is the correct answer to Question 5-14). Discussion Figure 11-12. 126 PART 2 CHEST A B Figure 4-71. The Radiology of Emergency Medicine. These lucencies are called bullae and, in centrilobular emphysema, have an upper lobe preponderance. Which of the following radiographic signs generally does not suggest the presence of pleural effusion? One simplified classification system divides congenital malformations into disorders of organogenesis (which include abnormalities of neural tube closure, diverticulation/cleavage, sulcation/cellular migration, and size, as well as destructive lesions acquired in utero), disorders of histogenesis (ie, neurocutaneous syndromes), and disorders of cytogenesis (ie, congenital neoplasms). Frontal chest radiograph (Figure 4-24) shows mild enlargement of the heart and indistinct vascularity, particularly at the lower lungs. New York: Elsevier; 2007. Case 10-11. The fat pads of the elbow are particularly helpful. Longitudinal US image of the normal liver, showing homogeneous parenchymal detail, the hyperechoic hemidiaphragmatic surface (∗), and portal triad (arrowhead). The penumbra (or unsharpness) of the shadow will depend not only on the source size, but also on the magnification, as can be illustrated by making a shadow of one’s hand on a piece of paper using a small light source such as a single light bulb. MR imaging findings are similar to those of CT, but as with CT, the lesion is inhomogeneous. Philadelphia: Lippincott; 1992. CHAPTER 8 an irregular narrowing at the rectosigmoid region, indicative of sigmoid carcinoma. In this case, a frontal chest radiograph (Figure 4-11) shows that the left hemithorax is opaque. E. catheter thrombosis. D. pulmonary artery aneurysm. Case 10-3. Fluoroscopy uses a fluorescent screen instead of radiographic film to view real-time images generated when an x-ray beam penetrates through a certain part of the body. Further examination yielded microscopic hematuria and history of frequent urination. Thus, diagnostic angiography may play a role in diagnosis of small-vessel renal disease such as polyarteritis nodosa. C. medial retinacular injury. Normally, these surfaces are smooth and are separated by a minimal amount of pleural fluid. In this case (Figure 4-20), the opacity involves multiple lobes bilaterally (A is the correct answer to Question 4-7.). The double-contrast effect is produced by coating the mucosal surface of the colon with a moderately dense, viscous barium suspension and distending the organ with air; a specially designed enema tip is needed for the examination. A maximum intensity projection (MIP) image from a PET-CT. If a diagnostic study is needed, a standard two-view mammogram is obtained first. The major initial pathologic process in RA is a synovitis that produces periarticular osteopenia because of the associated hyperemia. Semin Roentgenol. 2. Radiographically, joint disease may be diagnosed by any of the following: 1. All exercises include numerous images and specific questions focusing on common diseases or symptoms. Normal cerebral arteriogram. Diffuse lumpiness is not a contraindication to screening mammography, but when a particular lump becomes dominant, a diagnostic study is indicated. The raised metabolic rate can be used to distinguish neoplasm and inflammation from normal tissue. This mass is in the middle mediastinum. A. Gallstone ileus with gas in the biliary tree B. Hepatic portal venous gas C. Pneumoperitoneum D. Subdiaphragmatic abscess A 8-23. Sagittal T2-weighted fat-saturated MR image of the knee showing the normal homogeneously low-signal-intensity PCL (arrow). The process is accompanied by, first, increased resistance to normal hepatopetal (toward the liver) flow and, finally, the development of hepatofugal (away from the liver) flow. D. psoriasis. ALTERATIONS IN CARDIAC CONTOUR 3-6. 7. The esophageal mucosal surface has a smooth appearance when distended and shows smooth, thin longitudinal folds when collapsed (Figure 10-5 B). Two views of the duodenal bulb with the patient in a supine position demonstrating a posterior wall ulcer (u) with radiating folds extending around the circumference of the barium collection. Figure 7-9. Other patterns may occur. Ascites. Asymbolia or congenital insensitivity to pain, as exhibited in Case 7-3 (Figure 7-12), is a group of uncommon congenital disorders in which there is a variable degree of loss of pain sensation and is an unusual cause of neuropathic joints. Obstruction of smaller airways can occur as a result of mucous plugs, which are often present in intubated patients and in patients with chronic small airway disease. FOCAL LIVER DISEASES 11-5. As the vasculature tree ramifies, the arteries are closely related to the adjacent bronchus and are approximately the same size. The two lesions in the left tibia (arrows) represent the lesions that are causing cortical destruction in Figure 6-6. CT can usually, but not always, distinguish between epidural hematomas and subdural hematomas. Back Pain Figure 13-8. This band of heterotopia is known to be associated with intractable seizures, occurring earlier than in the focal type, as well as severe developmental delay. For this reason, CT was performed (Figures 13-26 A, B). The first is evaluation of fracture fragment position. variant is the isoechoic mass with hyperechoic periphery. CT examination of the injured limb and joints is used preoperatively for surgical planning and postoperatively to assess the results of surgical intervention. When this finding is encountered, MR imaging is the next most appropriate imaging test (B is the correct answer to Question 7-2). MR perfusion imaging is technically complex and requires advanced scanner and postprocessing software for image generation. (A–D) Case 4-14: 39-year-old female with a history of renal disease. The rotating gamma camera detects gamma rays emitted by the radiopharmaceutical and produces cross-sectional images of the brain that are really a map of brain perfusion (Figure 12-9). Except as permitted under the United States Copyright Act of 1976, no part of this publication may be reproduced or distributed in any form or by any means, or stored in a database or retrieval system, without the prior written permission of the publisher. In this chapter, I first describe the examination techniques that are currently available to evaluate the gastrointestinal tract. Like trauma to any other organ, injury to the liver varies from mild to severe. The resultant skull radiograph primarily gives information about the bones of the skull, but no direct information about the intracranial contents. 370 A PART 5 HEAD AND SPINE B Myelography is employed most commonly to evaluate for disk herniations and to rule out spinal cord compression caused by tumor or trauma. Crit. Figure 11-34. To exclude carcinoma, biopsy is needed. The stenosis in the left anterior descending coronary artery (arrow) has been reduced after percutaneous balloon angioplasty. (From Chen MY et al: Abnormal calcification on plain radiographs of the abdomen, The Radiologist 1999;7:65-83, used with permission). (B) On portal venous phase of CT, the mass demonstrates washout of contrast and an enhancing “pseudocapsule” (arrowheads) becomes apparent. In general, ureteral stones lie above and medially to the ischial spines, and they lack a radiolucent center. Mathematical calculations of the attenuation of the CT x-ray beam allow quantitative evaluation of the relative density of structures (ie, their Hounsfield units) and by using these “CT numbers,” much unique diagnostic information on the urinary tract is gained. 8-17. Case 8-1. The angiogram is similarly used in acute renal hemorrhage, acute arterial obstruction, and occasional renal mass management. High osmolar watersoluble contrast agents may cause severe pulmonary edema if aspirated. Calcifications of vas deferens. These can frequently be identified as granulomata because of characteristic patterns of calcification. Plain radiograph shows homogenous density of the gallbladder. Although MR urography is proving effective for many of the indications of CT urography, the excellent availability, reproducibility, and performance of CTU as well as the cost, time, and insensitivity to stone disease has limited the utility of MRU. In Case 9-3 (Figure 9-18), the most likely diagnosis is A. pheochromocytoma. Pyogenic liver abscess in a 55-year-old man with 3 days of fever, chill, and productive cough after right lobectomy. The energy of a light photon is of the order of one electron-volt (eV), whereas the average energy of an x-ray photon in a diagnostic x-ray beam is on the order of 30 kiloelectron volts (keV) and its wavelength is smaller than the diameter of an atom (108 cm). Salter-Harris classification of physeal injuries. The common radiographic findings in noncardiogenic edema are symmetric, diffuse areas of airspace filling that is often patchier in appearance and more peripheral in distribution. 10-7. A 65-year-old male with chronic epigastric pain. D. lung cancer. A retrograde cystogram would effectively demonstrate the presence of a bladder mass, but would do little to narrow the differential (B is incorrect). 6-4. The pancreas will develop calcifications within the ductal system (Figure 11-61). Nodular fixed narrowing of the gastric antrum associated with a small nodule at the base of the duodenal bulb (arrow). By the 1970s, other imaging modalities, including endoscopy and computed tomographic (CT) examination, appeared and have developed into alternate ways of imaging the hollow gastrointestinal organs. Noncardiogenic edema occurs as a result of disorders that increase pulmonary capillary permeability. The alveoli, or airspaces, that are normally filled with air have become filled with exudate. Infected necrosis is harder to identify on imaging studies than is pancreatic abscess, because it is less distinct and blends into the surrounding edema. These lesions are hamartomatous tumors of mesenchymal origin that are usually well differentiated and benign. In extremity imaging, mammographic technique is occasionally used to search for small calcifications or foreign bodies in the soft tissues. BRAIN AND ITS COVERINGS A CHAPTER 12 349 A B B Figure 12-21. Alterations in position and orientation of the kidneys may be related to congenital anomalies such as pelvic kidneys or may be secondary to mass effect from an adjacent lesion. Osteophytic ridging is a common manifestation of degenerative bone disease and in the cervical spine may cause myelopathy (if the cord is compressed) or radiculopathy (if a nerve root is compressed). Longitudinal US image of the normal biliary duct, showing the narrow caliber and the thin, uniform ductal walls (cursors denote the internal walls of the duct). Any sport that requires pivoting and planting of the feet places an enormous stress on the ACL and may cause injury to it. In this case (Figure 7-11), the capital femoral epiphysis on the right (arrow) is laterally displaced and smaller than the left epiphysis (arrowhead). CT is the most sensitive method of identifying pleural plaques (see Figure 4-48 A). C. carcinoma. In many cases, any of the modalities would be useful as a baseline examination, with the understanding that additional imaging might be required to answer all clinical questions. CT may be substituted for MRI if the latter is unavailable or there are contraindications to its use. 7-15. A. Fracture B. Dislocation C. Osteoarthritis D. None of the above B Figure 7-13. 4 NAME IT Damen Jeans Skinny Fit 140Dark Blue Denim POLLY Jeans; Verstellbarer Bund; Bequemer Stretchdenim; Materialzusammensetzung: 54% Baumwolle, 26% Polyester, 18% Viskose, 2% Elasthan; s.Oliver … SUGGESTED READING 1.

Axial CT image demonstrates the “signet ring” sign (arrow) of bronchiectasis created by the dilated bronchus (the ring) and adjacent artery. Mettler FA Jr, Huda W, Yoshizumi TT, Mahesh M. Effective doses in radiology and diagnostic nuclear medicine: a catalog. Note the numerous rounded echogenic foci with shadowing in the neck of the GB representing gallstones (arrow). MRI is also useful for detecting the soft-tissue extent of infection and for finding complications including abscesses or necrotic tissue. There is a large area of asymmetric architecture in this patient, but where the tumor ends is unclear. A. 11-20. In this case, the gallbladder is distended and the wall is thickened, measuring more than 5 mm, and has multiple lamina, indicating gallbladder wall inflammation from acute cholecystitis (A is the correct answer to Question 11-11). E. tumor. On the other hand, MR imaging is very sensitive in its ability to detect abnormalities in bone marrow. 4th ed. A 63-year-old man presents with severe upper neck pain not responding to antiinflammatory medication. 4-8. In fact, in some circumstances, it is not necessary to perform another test because of the limited potential yield from the examination or because there is no adequate therapy for the suspected abnormality. Note the fading margin along portions of the mass. Case 3-8: 75-year-old man with a history of a myocardial infarction 10 years earlier had this study done as a routine screening examination. Echocardiography is useful in assessing ventricular function, valvular heart disease, myocardial disease, pericardial disease, intracardiac masses, and aortic abnormalities (Figures 3-5 and 3-6). Transthoracic spectral Doppler tracing taken from an intercostal space over the cardiac apex. Renal cell carcinoma (RCC) is the most common primary renal malignancy, originating from the epithelium of the proximal tubule, having a male predominance and a peak incidence in adults in their 50s. A lateral decubitus chest radiograph, with the side containing the pleural effusion placed down (dependent), will demonstrate even smaller amounts of free-flowing pleural effusions (Figure 4-63 C). 10-20. G, gallbladder; pv, portal vein; P, pancreas; A, aorta; la, left adrenal gland; LK, top left kidney. This is a basic article for medical students and other non-radiologists. On US and CT, flow within an enlarged rounded vessel can be seen. In Case 12-5, what is the most likely diagnosis (Figure 12-18)? Because of its exquisite soft-tissue contrast, MR imaging allows radiologists to visualize subtle differences in soft tissues that had never before been seen with other imaging modalities. A description of the physics of MR imaging is beyond the scope of this chapter, and the reader is referred elsewhere for this information. PULMONARY VASCULARITY 3-11. EXERCISE 7-3. If all margins were to appear smooth, one acceptable course of action would be serial 6-month follow-up mammograms for a period of 2 years to demonstrate stability. SEIZURE AND EPILEPSY 12-18. Expiratory phase on a PA radiograph. As the gallbladder continues to accumulate bile, intraluminal pressure increases and vascular insufficiency of the wall occurs, causing ischemia, necrosis, and often supervening inflammation. However, CTA is also effective for detecting pseudoaneurysms related to pancreatitis. There was no reliable history of trauma. NEOPLASTIC SPINE DISEASE 13-4. Dynamic Radiology of the Abdomen: Normal and Pathologic Anatomy. With age, fibroadenomas become involuted and heavily calcified, thereby revealing their true identity (Figure 5-21). There is a joint effusion with a fat-fluid level (arrowheads). C. snowman appearance. In this case, the CT scan (Figure 12-34 A) shows extensive subarachnoid hemorrhage filling the basal cisterns, more pronounced on the right (black arrows), with extension of hemorrhage into the interhemispheric and Sylvian fissures. Discussion Although normal breast tissue is remarkably symmetric, it is never exactly the same on both sides. hernias are much less common, but may also be a cause of bowel obstruction. (A) Anteroposterior view. A 42-year-old man presents with mild abdominal pain. More importantly, the mucosal ring is probably the most common cause of solid food dysphagia seen in adults (the so-called steakhouse syndrome). Crystal Deposition Diseases Gout, a disorder more common in middle-aged men, is an inflammatory arthritis caused by abnormal deposition of urates (called tophi) in the soft tissues and cartilage. GASTROINTESTINAL TRACT A CHAPTER 10 285 B Figure 10-53. These erosions have “overhanging margins.” This radiographic appearance and the location of these changes at the first metatarsal phalangeal joint are characteristic of “podagra” associated with the initial attack of gout (C is the correct answer to Question 7-15). When the degree of edema is small to moderate, patients are often reasonably well compensated and are able to carry out many activities of daily living. The occurrence and severity of adverse reactions after administration of iodinated contrast material are unpredictable. The CT scan (Figure 4-70 C) demonstrates multiple small similar-sized cysts stacked along the lung periphery with some preservation of normal lung centrally, particularly on the right. Table 4-6. The anechoic, uniformly black area represents a simple cyst. 6-7. Finally, certain examinations are contraindicated in certain patients, and an alternative test must suffice. This mass corresponds to the palpable finding. They are chiefly useful for evaluation of the bones, but useful information about the adjacent soft tissues may also be obtained. A 57-year-old man who was beaten in the abdomen with a baseball bat. 266 PART 4 ABDOMEN Upper Gastrointestinal Tract The main indications for examination of the upper gastrointestinal tract include dysphagia, odynophagia, chest pain, pyrosis, suspicion of esophageal varices, dyspepsia, upper gastrointestinal bleeding, and evaluation of obstruction. Spot compression (Figure 5-20 A) reveals that portions of the border are not smooth, raising the level of suspicion for malignancy. The chest x-ray (Figure 4-70 A,B) shows diffuse bilateral coarse interstitial opacities with slight basilar predominance. Radiographs often show a joint effusion with preservation of the articular space and normal bone mineral density. 10-15. Serial abdominal films, however, should show a gradual reduction in the amount of free peritoneal air. Current state-of-the-art models are capable of acquiring 64, 128, or 256 channels of helical data 6 A PART 1 INTRODUCTION B Figure 1-4. Angiography has no role in the diagnosis of cholecystitis. With a new area of abnormality on physical examination, being in a high-risk age group (over 50 years old), and having a dense parenchymal pattern, the patient needs another mammogram, this time a diagnostic mammogram of the involved breast only. A. Three-dimensional postprocessed volume-rendered image of the urinary tract beautifully demonstrate the kidneys, ureters, and bladder. See Joints exercises computed tomography, 182 conventional tomography, 181–182 joint disease and, 185–186 magnetic resonance imaging, 183 radiography, 181 radionuclide imaging, 184–185 technique selection, 186 acute trauma, 186 congenital diseases, 186 nontraumatic cases, 186 subacute and remote trauma, 186 ultrasonography, 184 Joint trauma, 189–196 K Kerley line. Most commonly, digital receptors are used, although a receptor utilizing an intensifying screen and radiographic film remains in some use as well. (Continued) (B) Normal perfusion scan performed in seven projections, shows equal perfusion of radionuclide throughout all segments of the lungs. Discussion Two methods of dividing the mediastinum for radiographic purposes are in common use. Resting images performed using thallium-201. The arrowheads show a fragment of bone (posterior acetabulum wall) that was fractured during the posterior dislocation. Reflux of barium suspension into the ileum and the appendix, if present, occurs commonly. See Ductography Gallbladder calcification, 215 porcelain, 215, 216 US image of, 290 Gallium scans, 30 Gallstone ileus, 231–232 Gallstones, 213, 215, 312, 316 Gastric ulcer, 272 Gastrointestinal bleeding, 266, 272, 273 Gastrointestinal tract, 255 clinical exercises and case examples. If the gas shadow in the intestine is displaced to an unusual location, a soft-tissue mass, either inflammatory or neoplastic, may be suspected. Along with glandular elements, the parenchyma consists of ductal tissue. Infection Intracranial infections are best evaluated by contrast-enhanced MR imaging. The lobes are separated in whole or in part by pleural fissures. Congenital dislocation of the hips 2. The findings are typical for diverticulitis. C. intracardiac shunt. Zu den wichtigsten Untersuchungsmethoden von Radiologen zählen folgende Verfahren: Digitales Röntgen; Computertomographie (CT) Kernspintomographie; Magnet-Resonanz-Tomographie (MRT) Digitale Mammographie; Ultraschall; Es muss nicht immer Krebs sein, den … The “pencil-in-cup” deformity of the interphalangeal joint of the thumb in Case 7-17 (Figure 7-39) is most compatible with a diagnosis of A. psoriasis. Angiography may be used to study collateral formation in cirrhosis. Conventional Tomography Conventional tomography is mentioned mainly for historical interest. They may be painful as a result of irritation of an overlying bursa (Figure 6-27). A circumscribed mass representing carcinoma is seen less often than a spiculated mass. On plain abdominal films, the sigmoid volvulus forms an inverted U-shaped structure with the twisted sigmoid loops lying adjacent and having an oval appearance called the “coffee bean” sign. A 66-year-old woman is admitted with vague abdominal pain and vomiting. review of basic radiology a lange clinical book write a review dec 19 2008 meghan frick added it i personally liked this book because radiology is what i am majoring in flag 1 like like see review apr 29 2018 cosma catalin rated it it was amazing best book to learn basics in medical radio imagistic field flag obligatory basic radiology second. On a retrograde study, the more posterior urethra (prostatic and membranous) is often contracted and seen as a thin wisp of contrast. There is adjacent enlargement and heterogeneous enhancement of multiple lymph nodes (L). Compared to adenocarcinoma, these tumors have a less serious prognosis. Most (95%) of these fusions occur at the lower poles of the kidneys. The pleural surface of the aortopulmonary (AP) window is normally concave; convexity of the AP window suggests lymphadenopathy. B. EXERCISE 4-1. Metastatic Tumors A 163 overall survey for osseous metastases may be performed by nuclear medicine bone scan or by MRI. 12-14.
