Multidetector CT

Multidetector CT Not Yet Ready for Prime Coronary Time - CME Teaching Brief® - MedPage Today: "CLEVELAND, July 25 -- After a real-world multicenter evaluation with varying levels of expertise, the multidetector computed tomography (MDCT) got a thumb's down as a noninvasive competitor for coronary angiography.

Nearly 30% of the time, 16-row MDCT images of coronary artery segments were of too low quality to be evaluated, said Mario J. Garcia, M.D., of the Cleveland Clinic here. But 38% of patients with non-evaluable MDCT images turned out to have significant obstructive disease.

In addition, MDCT resulted in a high rate of false positives, Dr. Garcia and colleagues reported in the July 26 issue of the Journal of the American Medical Association.

Although single-center studies have reported promising results for MDCT in detecting obstructive coronary disease, few multiple-center studies have been done, the investigators said."
