Facility-wide program cuts CT dose by up to 90%

A San Diego imaging center was able to reduce CT radiation dose by as much as 90% using a combination of dose reduction strategies with or without iterative reconstruction techniques, thus minimizing patient risk, researchers wrote in the November Journal of the American College of Radiology.

Study shows pericardial fat is linked to calcified plaque

Thursday, November 29 | 11:50 a.m.-12:00 p.m. | SSQ01-09 | Room S502ABPatients with higher levels of pericardial fat are also more likely to have more coronary artery calcium and, hence, greater risk of cardiac events, say researchers from the University of California, San Francisco.
