Analysis of thallium-201 myocardial SPECT images using fuzzy set theory.

abstract：OBJECTIVE:The potential of positron emission tomography/computed tomography using 62Cu-diacetyl-bis (N4-methylthiosemicarbazone) (62Cu-ATSM PET/CT), which was originally developed as a hypoxic tracer, to predict therapeutic resistance and prognosis has been reported in various cancers. Our purpose was to investigate pr...
