VC is cost-effective for screening; tiny polyps can be ignored

Virtual colonoscopy is a cost-effective way to screen for colorectal cancer -- provided that individuals with tiny lesions aren't referred for polypectomy, according to the results of a new study from France.

Virtual colonoscopy preferred for surveillance follow-up

Patients referred for polyp surveillance after virtual colonoscopy are more likely to opt for another VC exam at follow-up, Italian researchers report. But patients want their follow-up scans sooner rather than later.

High-pitch cardiothoracic CTA skips breath-holds and high doses

A new way to use CT angiography (CTA) to scan fast-moving targets -- such as fidgety children and grown-ups with rapid heartbeats -- is becoming routine at a hospital in France.

CARS report: New CAD tool follows lung nodules over time

BERLIN - It's easy to complain about the insanity of tracking lung nodule changes in multiple CT scans over time, but at least one group is doing something about it, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.

CARS report: Novel conebeam CT cuts breast dose, improves accuracy

BERLIN - Dual-resolution conebeam CT accentuates the positives of conebeam breast imaging and eliminates (some of) the negatives, said a team from Texas in a presentation at the Computer Assisted Radiology and Surgery meeting.

CARS report: Personalized medicine will dominate future care

BERLIN - Medicine is undergoing a historic transition, moving away from a cookie-cutter model of care and toward individualized treatment strategies based on patient-specific models of disease and treatment. Imaging, biology, and mathematics are at the center of this new paradigm, according to Dr. Michael Vannier, who spoke at the opening of the 2009 Computer Assisted Radiology and Surgery (CARS) meeting.

Readers undaunted by VC CAD false positives

Radiologists examining data from virtual colonoscopy studies can easily dismiss increasing numbers of false-positive detections generated by computer-aided detection (CAD) systems, researchers from the U.K. report. But the presence of more false positives makes reading less efficient.

MR stress alone sufficient for myocardial perfusion

Use of an automated postprocessing tool eliminates the need for both a stress and rest exam in myocardial perfusion MRI, according to researchers from Germany. They found that quantitative assessment of stress MRI images alone delivers the same diagnostic performance as semiquantitative evaluation of both stress and rest perfusion exams.

Virtual colonoscopy CAD improves flat-lesion detection

Computer-aided detection (CAD) software can improve the detection of flat lesions at virtual colonoscopy -- as long as the lesions are at least 1 mm high. In a new study from Italy, CAD detected 94% of all flat lesions; however, radiologists dismissed a few of them incorrectly as false positives.
