Quantitation of regional ejection fractions using gated tomographic imaging with 99mTc-sestamibi.

Background: Gated single photon emission CT (SPECT) sestamibi imaging allows the simultaneous assessment of myocardial perfusion and left ventricular function.

Objective: The purpose of this study was to evaluate a technique for quantitative regional wall motion assessment using gated SPECT (99m)Tc-sestamibi imaging.

Patients And Interventions: Fourteen subjects without cardiac pathology and 25 patients who had experienced myocardial infarction (MI) were studied.
