Radionuclide myocardial perfusion imaging has been established as a noninvasive method for diagnosis of coronary artery disease. The assessment of myocardial perfusion imaging can be done by either qualitative or quantitative analyses. Through use of both types of analyses, clinically useful reproducible interpretation of myocardial perfusion images requires considerable operator experience. Th...
BACKGROUND AND PURPOSE The mismatch lesion volumes defined by perfusion-weighted imaging exceeding diffusion-weighted imaging have been used as a marker of ischemic penumbral tissue. Defining the perfusion lesion by thresholding has shown promise as a practical tool; several positron emission tomography studies have indicated a more probabilistic relationship between perfusion and infarction. H...
