Wider 3D viewing angle may aid polyp detection
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.

Automated polyp measurement supports risk assessment
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.

ROI changes colorectal tumor perfusion measurements
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.

Image tools cut false positives in unprepped VC
Aiming to optimize the results of prepless vitual colonoscopy, researchers have developed a pair of tools to process unprepped CT data and make it easier to read. According to the results of a pilot study, the methods reduced false positives by as much as one-third.

FOBT-screened cohort yields too many positives for VC
Virtual colonoscopy (VC) seems a promising way to sort through patients with a positive fecal occult blood test (FOBT), considering the latter's demonstrated low sensitivity and high false-positive rate. But in a screening cohort from the Netherlands, polyps and cancer were so common in FOBT patients that VC hardly seemed worth it.

Higher VC laxative dose burdens patients, doesn't improve reads
Researchers from the Netherlands report that higher levels of catharsis conferred neither better image quality nor improvement of tagging characteristics on image data, compared to images from subjects given lower laxative doses.

CARS report: Fuzzy theory yields sharper CTA images
BARCELONA - Coronary CT angiography isn't as easy to perform as it could be, according to Chunliang Wang, who discussed the problem of hidden coronary arteries and introduced a novel segmentation method that might make them easier to examine at the 2008 Computer Assisted Radiology and Surgery (CARS) meeting.

CARS report: CAD prompts range of behaviors in readers
BARCELONA - How computer-aided detection (CAD) software works in theory is one thing, and how it functions in practice is another, as radiologists who use CAD have come to appreciate. But the ways in which readers react to CAD prompts, a subject that has received scant attention, has important implications for both CAD design and reader training.
