CT angiography of the hepatic and pancreatic circulation.

Multidetector computed tomography angiography (MDCTA) is an established, noninvasive, and effective imaging method to evaluate the liver and the pancreas primarily for neoplasm staging and presurgical planning. However, its role has also extended into a variety of other clinical indications. Technological advances in MDCT scanners and post processing now offer new opportunities with CTA, but the challenges of protocol optimization should be confronted appropriately to meet the new expectations.

Debate: diminutive polyps noted at CT colonography need not be reported.

Colorectal polyps less than 6 mm in size pose a negligible risk to the development of colorectal carcinoma. The sensitivity and specificity for detection of diminutive lesions on all available examinations including CT colonography (CTC) and optical colonoscopy (OC) is relatively low. In the context of regular screening, the low clinical significance and slow to negligible growth of diminutive polyps, as well as the low detection performance of CTC and OC for these lesions, would contribute to wasted health care resource and excess morbidity if each diminutive polyp were referred for potential resection.

MDCT of acute mild (nonnecrotizing) pancreatitis: abdominal complications and fate of fluid collections.

Objective: The objective of our study was to describe the occurrence of local complications and the fate of fluid collections in milder forms of acute nonnecrotizing pancreatitis.

Materials And Methods: Initial MDCT studies of 169 consecutive patients with mild acute pancreatitis and 203 follow-up CT examinations were reviewed. The fate of peripancreatic fluid collections was investigated, and the incidence and type of local complications were recorded and correlated to the CT grading system (A-E).
