After ruling out of ACS, rest/stress positron emission tomography (PET) or single-photon emission computed tomography (SPECT) myocardial perfusion imag-ing (MPI) are helpful for detection of perfusion abnormalities, measures of left ventricular function, and high-risk findings, such as transient ischemic dilation. For PET, calculation of myocardial blood flow reserve (MBFR, the ratio of peak hyperemia to resting myocardial blood flow) adds diagnostic and prognostic information over MPI. Radiation exposure dose is ∼3 mSv for rest/stress PET with Rb-82 and ∼10 mSv for Tc-99m SPECT.
