CT features diagnose autoimmune pancreatitis

Autoimmune pancreatitis is a rare form of pancreatitis characterized by diffuse or focal enlargement of the gland, periductal inflammation, fibrosis, and vasculitis -- often accompanied by other autoimmune disease and nonspecific symptoms. But according to researchers from Italy, the condition can be reliably characterized on biphasic or triphasic CT.

CT, CE are better choices for small-bowel Crohn's

A study comparing four exam techniques chose CT and capsule endoscopy (CE) as best of show for diagnosing Crohn's disease in the small bowel. Ileoscopy came in third and has its uses, the authors noted, while the small-bowel follow-through exam showed significant limitations, often producing negative or inconclusive findings.

VC fluid tagging optimized with barium on day of exam

Barium does a good job of tagging fluid and residual fecal material for virtual colonoscopy, although tweaking the dose and timing don't do much to reduce the small amount of stool that remains untagged, researchers from Belgium reported in a recent study. But adding a small extra dose of barium on the day of the VC exam can improve fluid tagging.

High resolution, fast acquisition give 3D MRA edge in abdomen

By Shalmali Pal

Three-dimensional contrast-enhanced MR angiography (CEMRA) at 3 tesla is "extremely promising" for evaluating abdominal vasculature, according to researchers from the University of California, Los Angeles. The advantages of 3D CEMRA at 3 tesla include improved spatial resolution and a higher signal-to-noise ratio (SNR).

Contrast-enhanced US useful for differentiating focal liver lesions

By Radiology Review

(Radiology Review) All three vascular phases should be assessed when sonographic contrast agents are used to differentiate benign from malignant focal liver lesions, according to researchers from Spain. They evaluated the accuracy of tumoral vascularity display in liver tumors using contrast-enhanced sonography.

Chemical shift MRI improves detection of adrenal adenomas

By Radiology Review

(Radiology Review) Whether a coexisting adrenal mass is an adenoma or metastasis affects treatment of extra-adrenal primary tumors, according to researchers from Turkey. They report in the American Journal of Roentgenology that chemical shift MRI can help differentiate adrenal adenomas from nonadenomas and metastases.

Prepless VC misses some diminutive flat lesions

A rather gutsy clinical study by Italian radiologists pitted state-of-the-art chromoscopic high-magnification colonoscopy against prepless virtual colonoscopy. The researchers found that advanced colonoscopy did a better job of identifying flat lesions, particularly the smallest ones.

Early postoperative US predicts liver transplant complications

By Radiology Review

(Radiology Review) The hepatic artery resistive index can predict vascular and nonvascular complications in adult liver transplant patients, according to a study published in the American Journal of Roentgenology. The authors highlight the importance of early detection of hepatic artery stenosis or thrombosis with ultrasound to enable timely revascularization.
