Radiation exposure varies widely during 64-slice cardiac CT

February 3, 2009 Diagnostic Imaging. By James Brice An international clinical trial involving 50 healthcare facilities and nearly 2000 patients has found that physicians often do not apply available dose reduction strategies in procedures, resulting in a wide variation in radiation exposure. Investigators involved in the Prospective Multicenter Study on Radiation Dose Estimates of Cardiac CT Angiography in Daily Practice I study (PROTECTION I) were encouraged by the median 12-mSv effective dose for the 1965 patients scanned in selected one-month periods from February to December 2007. Participants were drawn from 21 academic and 29 community hospitals in Europe, the U.S., Asia, and South America.
