Adverse events weigh on colonoscopy mortality equation
Does optical colonoscopy produce a mortality benefit? Dr. David Lieberman, chief of gastroenterology at Oregon Health and Science University in Portland, tackled the question at the recent American Society of Clinical Oncology's Gastrointestinal Cancers Symposium in San Francisco.

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.

Doppler US accurate for spectrum of aortic valve measurements
Doppler ultrasound is accurate for measuring aortic stenosis, even in the small subgroup of patients with severely reduced left ventricular ejection fraction, according to French and Canadian researchers in the Journal of the American College of Cardiology.

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.

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.

Step-and-shoot acquisition cuts CTA dose, improves images
Low-pitch helical acquisition is effective for ensuring complete volume coverage and good phase registration over multiple cardiac cycles. But it packs a high radiation dose and lacks flexibility for irregular heart motion. Researchers have found a potential solution with a "step-and-shoot" acquisition mode for 64-slice CT scanners that can reduce even a modulated dose by 50% or more.

CT is the blanket modality for neuroimaging blunt injury patients
SAN FRANCISCO - In case you had any doubts, technology and urgent care practice are increasingly headed toward a single conclusion: CT is all you need to image neurological injuries, including the head, the spine, and even ligamentous trauma.

MDCT still can't differentiate between noncalcified plaques
Thin-section multidetector-row CT does a fine job of visualizing calcified atherosclerotic plaque, but is all but blind when it comes to differentiating two important but morphologically distinct types of noncalcified coronary plaque.
