DR for small-bowel exams: What's not to like?
By Brian Casey
A group of Israeli researchers compared a digital radiography (DR) system to analog film-screen x-ray for small-bowel follow-through studies and found the DR system superior in image quality, radiation dose, and workflow.

ACRIN trial shows VC's accuracy comparable to optical colonoscopy
By Eric Barnes
The New England Journal of Medicine today published results from the first large multicenter trial on the efficacy of virtual colonoscopy. The accuracy of the imaging-based exam was comparable to that of optical colonoscopy for the detection of adenomatous colorectal polyps 1 cm and larger.

Wider 3D viewing angle may aid polyp detection
By Eric Barnes
Virtual colonoscopy readers saw a greater percentage of the colonic mucosa by increasing the field-of-view on their 3D software to match that of a standard colonoscope. However, the wider viewing angle may have also reduced polyp conspicuity and increased distortion, with unknown effects on detection sensitivity.

ROI changes colorectal tumor perfusion measurements
By Eric Barnes
The development of automated perfusion-mapping software for CT data has opened up intriguing possibilities for the assessment of tumor vascularity, specifically for monitoring response to antiangiogenic drug treatment. But where, precisely, to measure tumor vascularity is a question that had not been addressed, according to U.K. researchers.

Automated polyp measurement supports risk assessment
By Eric Barnes
Automated polyp-measurement software performed as well as human readers in a study that could lead to more efficient screening with virtual colonoscopy. The study sought to evaluate the accuracy of an automated polyp size measurement tool and its effectiveness for risk stratification in 305 subjects.
