Absolute Myocardial Blood Flow via Single-Time-Point Imaging in PET and SPECT: Cross-Validation Against Dynamic 13N-Ammonia PET.
BACKGROUND Quantitative assessment of myocardial blood flow (MBF) and flow reserve (MFR) is clinically superior to relative imaging but limited by dynamic scanning requirements. We evaluated a novel single-time-point (STP) method to estimate MBF from a single static image using a population-based power law model of the...
