Subendocardial versus transmural ischaemia in myocardial perfusion SPECT – a Monte Carlo study

Myocardial perfusion imaging with single‐photon emission computed tomography (SPECT) is useful for the evaluation of patients with known or suspected coronary artery disease. Parameters of interest are the reduction in the blood perfusion (severity) and the lesion volume (extent). The aim of this study was to evaluate these parameters, as calculated by automatic quantification software, for different cases of subendocardial and transmural myocardial lesions.
