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.

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.

MRI enterography shows shortcomings for Crohn's disease
By Wayne Forrest
Although MRI enterography can diagnose important incidental findings in a minority of patients with suspected or known Crohn's disease, Dutch researchers have concluded that a substantial number of patients experience unnecessary morbidity because of additional examinations of benign or normal conditions.

320-row perfusion CT shows promise for pancreatic tumors
By Eric Barnes
Perfusion CT with a 320-detector-row scanner offers improved resolution of pancreatic tumors due to its ability to image the entire organ without slice overlap, according to researchers from Berlin and Toronto.

New VC CAD algorithm reveals submucosal colon cancers
By Eric Barnes
A new computer-aided detection (CAD) algorithm goes beyond flat-polyp detection to find submucosally invading colorectal cancers with virtual colonoscopy. Researchers say the software offers an important alternative to traditional CAD feature classification that could improve the sensitivity of all VC studies.

Experience counts when reading contrast ultrasound liver images
By Erik L. Ridley
Radiologists with experience reading contrast-enhanced ultrasound images have the upper hand over neophytes in characterizing malignant liver tumors, according to research published in the January issue of the Journal of Ultrasound in Medicine.

Growth rate of small abdominal aortic aneurysms predicts need for intervention
By Reuters Health
NEW YORK (Reuters Health), Jan 7 - Only about half of small abdominal aortic aneurysms will increase in size, and those that grow less than 1.5 mm per year are seldom of clinical relevance, new research suggests.

Ultrasound elastography characterizes fibrosis severity
By Erik L. Ridley
A Spanish research team has found that ultrasound elastography can reliably differentiate between rapid or slow fibrosis in liver transplant patients, paving the way for earlier identification of patients at risk of hepatitis C recurrence.
