Assessment of transient ischemic dilation (TID) ratio in gated SPECT myocardial perfusion imaging (MPI) using regadenoson, a new agent for pharmacologic stress testing
Journal of Nuclear Cardiology, 05/16/2012
Katz JS et al. – The mean transient ischemic dilation (TID) ratio in patients with multi–vessel disease was 1.19. The threshold for an abnormal TID was 1.39 with specificity of 95% and sensitivity of 15% for determining multi–vessel coronary artery disease (CAD) status. Authors conclude that the level of TID in gated SPECT myocardial perfusion imaging (MPI) using regadenoson is associated with the degree of CAD on angiography.
