Myocardial viability studies using fluorine-18-FDG SPECT: a comparison with fluorine-18-FDG PET.

Abstract

Despite its markedly inferior physical imaging characteristics compared with PET, SPECT with the dedicated 511-keV collimator offers a low-cost, practical alternative to PET in studying myocardial viability using [18F]FDG. SPECT systems with a high-energy, general-purpose collimator, on the other hand, are inadequate in such studies.
