After ruling out of ACS, rest/stress positron emission tomography  (PET)  or single-photon emission computed tomography  (SPECT)  myocardial  perfusion  imaging (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.
