SPECT-MPI in the PCP setting still offers high prognostic value

March 21, 2013

SPECT-myocardial perfusion imaging (SPECT-MPI) performed at a low-volume primary care physician’s (PCP’s) office has robust prognostic value in line with what is reported in tertiary or high-volume practice settings, according to a study published March 9 in Journal of Nuclear Cardiology .

While studies have shown the prognostic value of SPECT-MPI—patients with normal MPI have an annual risk of less than 1 percent for major adverse cardiovascular events—those studies were conducted in larger tertiary or high-volume centers, explained Rami Doukky, MD, MSc, of Rush University Medical Center in Chicago, and colleagues. Mobile cardiac SPECT imaging equipment has made the technique easier to conduct in a PCP’s office, but little was known about the value of studies in this setting or whether PCPs would consistently follow appropriate use criteria.
