VC shows extracolonic findings in most patients

Most people -- even those at average risk for colorectal cancer -- have extracolonic findings at virtual colonoscopy, including significant numbers with clinically important conditions, according to a new study from the Veterans Affairs Medical Center in San Francisco.

VC earns high marks in symptomatic kids

In what may be the first peer-reviewed study of virtual colonoscopy in children, researchers from Diagnóstico Maipu in Buenos Aires have produced high sensitivity and specificity with a low-dose VC protocol, compared to optical colonoscopy.

VC holds up against back-to-back colonoscopies

Virtual colonoscopy's accuracy is hard to verify because it is usually compared against the imperfect gold standard of optical colonoscopy. But in a new study, researchers in Italy compared the results of VC to those of back-to-back colonoscopies and may have achieved the best reference standard so far for VC.

Part I: Computer-aided detection marking new targets

By Wayne Forrest

When healthcare practitioners think of computer-aided detection (CAD) technology today, they usually consider using it with mammography for early breast cancer detection. As technology and research progress, however, there is a developing consensus among radiologists that CAD can aid in uncovering abnormalities in applications such as breast MRI, lung cancer screening, and virtual colonoscopy exams.

Reduced prep, low-residue diet, and mild tagging suffice for accurate VC

High barium doses aren't necessary for reduced-prep virtual colonoscopy when a low-residue diet is part of the protocol. In the American Journal of Roentgenology, researchers from Belgium reported high sensitivity and specificity for colorectal polyps using such a protocol.

Small hepatic lesions mostly benign in female breast cancer patients

By N. Shivapriya

In female breast cancer patients, interval follow-up imaging rather than imaging workup or biopsy should be performed for hepatic lesions that are "too small to characterize" (TSTC) on CT. More so if it is stage 0 breast cancer and there are no clinical findings supporting suspicion of liver metastasis, according to recommendations by researchers from the Memorial Sloan-Kettering Cancer Center in New York City.

VC CAD matches prone and supine imaging data

Rewriting a page from standard clinical practice, CAD developers are using automated matching of prone and supine virtual colonoscopy datasets as their primary method of reducing false-positive candidates. And the nascent technique worked reasonably well, so long as the data were relatively free of collapsed segments and residual fecal matter.
