CT calcium scoring alters cardiac risk estimates
By Eric Barnes
Ten-year outcomes data from the Rotterdam coronary artery calcium (CAC) study underscore the prognostic power of adding CAC to a traditional risk stratification method. New results in the Journal of the American College of Cardiology show that CAC scores frequently change the risk category for future coronary events in asymptomatic individuals.

Aortic root dilation in athletes requires close surveillance
By Reuters Health
NEW YORK (Reuters Health) - Aortic root dilation is uncommon in highly trained competitive athletes and is not likely to be caused by exercise training. Consequently, aortic root dilation in this population is probably pathologic and shouldn't be dismissed, according to findings published in the August 17 online issue of Circulation.

Advanced CT may have role in noncalcified plaque assessment
By Eric Barnes
Advanced MDCT scanning may be ready to play an important role in assessing noncalcified coronary artery plaque, say German researchers, who used a 256-detector-row scanner and plaque-volume measurement software to compare interobserver variability in patients with different types of plaque.

Cardiac MRI shows how triathletes' hearts adapt
By Wayne Forrest and Eric Barnes
With the help of 1.5-tesla cardiac MRI, German researchers have found that the human heart adapts to triathlon training by developing greater muscle mass and wall thickness, as well as larger left atria and larger right and left ventricles, according to a study to be published in the October issue of Radiology.
