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.

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.
