JACC Feature: MPI studies responsible for 74% of cumulative rad dose

Web Exclusives | Monday, July 12 2010
Written by Manjula Puthenedam
Cardiac imaging procedures represent an important source of ionizing radiation in the U.S., and the distribution of cumulative effective doses can lead to sizable radiation exposure for many individuals, according to a study published online July 7 in the Journal of the American College of Cardiology. Better strategies to minimize the radiation exposure from cardiac imaging procedures should be encouraged, said the study's lead author Jersey Chen, MD, in an interview.
 

JACC: Can SPECT perfusion imaging predict sudden cardiac death?

Clinical Studies | Thursday, July 08 2010

CMS Webinar: Incentive payments to offset EHR adoption, not reimburse
