Gated Myocardial Perfusion SPECT

Abstract

Computer advances in the field of nuclear cardiology in the 1990s allowed the technology of gated myocardial perfusion SPECT to become a routine part of myocardial perfusion SPECT assessment. With this approach, accurate measurements are made of left ventricular end-diastolic and end-systolic volumes as well as of left ventricular ejection fraction. Additionally, this method provides a validated technique for assessing regional ventricular function both at rest and following stress. From a variety of vendors, software approaches have been developed which allow quantitation of volumes and ejection fraction, adding to the objectivity of analyses provided by gated SPECT assessments. Due to the complementary nature of assessments of perfusion and function, acceptance of gated SPECT has been rapid in clinical nuclear cardiology.KeywordsRight VentricularNuclear CardiologyPerfusion DefectMyocardial Perfusion SPECTTransient Ischemic DilationThese keywords were added by machine and not by the authors.
