Current Problems in Diagnostic Radiology RSS feed: Current Issue. Current Problems in Diagnostic Radiology covers important and controversial topics in radiology. Each issue presents important viewpoints from leading radiologists. High-quality reproductions of radiographs, CT scans, MR images, and sonograms clearly depict what is being described in each article. Also included are valuable updates relevant to other areas of practice, such as medical-legal issues or archiving systems. With new multi-topic format and image-intensive style, Current Problems in Diagnostic Radiology offers an outstanding, time-saving investigation into current topics most relevant to radiologists. http://www.cpdrjournal.com/?rss=yesElsevier Inc.en © 2012 Mosby, Inc. All rights reserved.

Despite certain inherent limitations in evaluating chronic liver disease on routine gray-scale US, it is still widely used for the initial evaluation in patients suspected of liver disease as well as for hepatocellular carcinoma (HCC) screening in patients with known cirrhosis. Due to recent advances in digital technology and US imaging software, various new computer protocols have been incorporated in the new US equipment. This in turn has resulted in a great improvement in image quality and image resolution. Consequently, the increased ability of US to better characterize the liver texture in general has enabled the sonographers to identify subtle changes in the liver texture and delineate smaller masses in the liver with greater success.

Incidence, patient-, and procedure-related risk factors, pathogenesis, and clinical manifestations of extravasation injuries are discussed with a review of recent literature, and a practical preventive approach is proposed. A diagnostic and therapeutic protocol, to be applied whenever contrast extravasation is detected, includes radiographic assessment of compartmentalization, antidote application, local care, and clinical follow-up; indications for surgical consultation and adverse event reporting are provided.

The specific signature of macroscopic fat on computed tomography along with the usually characteristic findings of these entities makes the diagnosis of most of these conditions relatively straightforward. In the intestinal tract, the “fat halo sign” usually arises in the context of subacute to chronic bowel wall inflammation. Excess fat in the renal sinus may occur with renal sinus lipomatosis or “replacement lipomatosis of the kidney.” Some cases of “pancreatic lipomatosis” may culminate in steatopancreatitis and ultimately neoplastic transformations. “Fibrofatty mesenteric proliferation” is a characteristic feature of Crohn disease. In the setting of the acute abdomen, accurate diagnosis of fat-containing lesions (epiploic appendagitis or omental infarction) from other causes of the acute abdomen is critical. Mesenteric panniculitis is 1 of the causes of the “misty mesentery.” Juxtacaval fat deposition is a benign process that has the potential to be confused with more serious conditions. More diffuse fat deposition (abdominal or pelvic lipomatosis) has the potential to become symptomatic by causing mass effect upon the adjacent structures. Fat can also be seen in a variety of postoperative/iatrogenic conditions or abdominal wall/diaphragmatic hernias.

Some of these tumors may demonstrate typical imaging features. However, due to the rarity of these tumors, imaging characteristics of these diverse lesions are not well described in the literature. Knowledge of these select ovarian entities is essential and facilitates optimal management of patients who often manifest with nonspecific symptoms.
