CO2 volumes higher than previous reports in VC
By
Eric Barnes
Using more CO2 to insufflate the colon during virtual colonoscopy doesn't produce better distention, but patients with ileocecal valve incompetence -- most patients presenting for screening -- require more insufflation, say researchers from Ireland.

CT-based Crohn's diagnosis takes aim at endoscopy
By
Eric Barnes
GENEVA - Japanese researchers hope to supplant the invasive and time-consuming process of diagnosing Crohn's disease with a CT technique that is unaffected by intestinal stenosis and other impediments to conventional endoscopic evaluation.

Dual-energy VC aims for noninvasive polyp evaluation
By
Eric Barnes
Dual-energy CT may find itself forging a new path in virtual colonoscopy by not only finding colorectal lesions but characterizing them in ways other noninvasive techniques cannot, according to a presentation at the International Society for Computed Tomography conference.

Nonlaxative PET/CT colonography is both feasible and effective
By
Eric Barnes
For individuals who need a highly accurate colon screening exam but can't tolerate a full bowel prep, nonlaxative PET/CT colonography may be just what the doctor ordered, according to a new study from the U.K. published this month in the
Journal of Nuclear Medicine

VC shows high diagnostic yield after failed colonoscopy
By
Eric Barnes
Virtual colonoscopy finds significant pathology in patients referred after failed colonoscopy, according to a study presented at the Digestive Disease Week meeting in New Orleans. The results show the need for a complete colon exam and highlight VC's strengths in detecting extracolonic abnormalities.

By
Wayne Forrest
FDG-PET/CT has a "significant role" in characterizing suspected colorectal cancer recurrence at an early stage, according to a study presented by U.K. researchers at the American Roentgen Ray Society meeting this week in San Diego.

Flexible sigmoidoscopy of dubious value after VC
By
Eric Barnes
The yield of additional pathological findings was quite low in a group of symptomatic patients who underwent flexible sigmoidoscopy after virtual colonoscopy screening, according to a poster presentation at this week's Digestive Disease Week meeting in New Orleans.

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%.
