PET (positron emission tomography) beats SPECT (single photon emission computed tomography) as heart risk diagnostic

This article was originally published in Clinica

Executive Summary

Positron emission tomography (PET) scanning is more accurate, less invasive and more cost effective than single photon emission computed tomography (SPECT) imaging when used as the first tool to diagnose cardiac vessel blockages. So suggest the results of a trial conducted at the State University of New York, published in the July edition of the Journal of Nuclear Medicine. Lead researcher Dr Michael Merhige, clinical associate professor of nuclear medicine at the university, said that the researchers found a more than 50% decrease in the use of invasive coronary arteriography and coronary artery bypass grafting when PET was used as the first-line test.
