One-time sigmoidoscopy screening prevents colorectal cancer
By Reuters Health
NEW YORK (Reuters Health), Apr 28 - Flexible sigmoidoscopy reduces colorectal cancer incidence and mortality, British researchers reported online April 28 in the Lancet. Offered once to people ages 55 to 64, the procedure lowered the incidence of colorectal cancers by as much as one-third and cancer-specific mortality by up to 43%.

3T MRA protocol has value but falls short in abdominal vasculature
By Wayne Forrest
A time-resolved 3-tesla MR angiography (MRA) technique that uses less contrast dose than conventional high-resolution MRI has some advantages in the abdominal aorta, but its lower signal-to-noise ratio means it probably won't supplant conventional MRA, according to a study in the May Academic Radiology.

Small colon polyps on VC suggest presence of larger lesions
By Eric Barnes
Individuals with several diminutive colon polyps on virtual colonoscopy studies are far more likely than other screening subjects to also have a larger colorectal lesion, say researchers from the University of Munich in Germany.

Computer analysis bolsters liver elastography performance
By Erik L. Ridley
Computer-enhanced dynamic analysis of ultrasound elastography movies is a useful and reliable method for depicting liver hardness, yielding a high level of interreader agreement, according to research published April 14 in the World Journal of Gastroenterology.

CT shows abdominal fat is unreliable Crohn's treatment target
By Eric Barnes
A few reports have associated abdominal visceral fat with more aggressive forms of Crohn's disease, but the strength of the association -- and the implications for treatment -- remain unclear. Researchers from Ireland decided to try CT to resolve the issue.

Open-source software increases colon polyp conspicuity
By Eric Barnes
Visibility of colon polyps is increased and sensitivity improved with the use of threshold-based color-coding software in virtual colonoscopy, according to a new study from Italy. Even flat lesions were more often visible with use of the open-source 2D-based interpretation software.

Blood infection risk extremely low with VC
By Eric Barnes
The risk of bloodstream infections such as bacteremia leading to endocarditis is extremely low in virtual colonoscopy -- in fact, infection rates are probably even lower than in conventional colonoscopy, say researchers from Ireland, the U.K., and the U.S.

Diverticular disease favors prone over supine VC images
By Eric Barnes
Diverticular disease, an unfortunate result of low-fiber Western diets that increases in incidence with age to burden most of the elderly population, has a friend in virtual colonoscopy. That's because VC generally provides an easier colon exam for both patient and provider than conventional colonoscopy.

Yttrium-90 microspheres prolong survival with advanced liver cancer
By Reuters Health
NEW YORK (Reuters Health), Mar 18 - Radioembolization with yttrium-90 microspheres is a noninvasive treatment option for patients with inoperable primary hepatocellular carcinoma, researchers reported at this week's Society of Interventional Radiology meeting in Tampa, FL.

One-day bowel prep eases VC for patients, providers
By Eric Barnes
VIENNA - A one-day bowel prep and virtual colonoscopy exam regimen offers sufficiently good image quality, making life easier for both patients and providers compared to a multiday regimen, according to a study presented Sunday at the European Congress of Radiology.

320-row CT minimizes dose in pediatric abdominal studies
By Eric Barnes
It's no secret that CT radiation dose levels in children -- especially in the emergency department, where patients are fidgety and physicians need fast answers -- are too high. One solution, investigated by researchers from Toronto and Berlin, is wide-area-detector scans with 320-detector-row CT.

VC obviates need for colonoscopy even in symptomatic patients
By Eric Barnes
Even among individuals with symptoms suggesting a higher risk of colorectal polyps and cancer, virtual colonoscopy screening is enough to prevent most of them from having to undergo invasive colonoscopy, according to a recent study from the Netherlands.
