VC CAD improves results for readers at all levels
By Eric Barnes
Virtual colonoscopy computer-aided detection (CAD) studies in recent years have shown promising results for the detection of colorectal polyps and cancer. But do CAD results actually improve reader performance? A group of radiologists in the U.K. sought to answer the question by assessing how VC CAD affects patient classification, polyp detection, and reading times. They found that VC CAD improved reader performance -- significantly and fairly evenly -- at all levels.

3-tesla MR shows promise for abdominal, pelvic imaging
By Jonathan S. Batchelor
PHOENIX - Three-tesla MRI offers improved signal-to-noise and contrast-to-noise ratios compared with 1.5-tesla for body imaging, according to a presentation at the 2006 Society of Computed Body Tomography and Magnetic Resonance (SCBT/MR) meeting. However, several issues such as cost, weight, safety, and modified imaging protocols may mitigate these advantages.

MRI phase-mapping quantifies regional wall motion
By Eric Barnes
The assessment of myocardial wall motion plays a key role in diagnostic and therapeutic decision-making, but wall motion is extremely difficult to assess quantitatively. Physicians from Oxford University in the U.K. believe they've found a comprehensive and reproducible method of assessing regional wall motion in tissue with phase mapping (TPM) of MRI data, a technique based on phase velocity.
