Radionuclide angiography for the evaluation of anthracycline therapy.

A sensitive and reproducible method to noninvasively monitor cardiac function in patients receiving anthracycline therapy is badly needed. The radionuclide ejection fraction (EFrn) appears to be a suitable technique to provide this hemodynamic information. This paper describes the technique for determining the left ventricular EFrn with the use of technetium99m-labeled rbcs, a gamma scintillation camera, and a dedicated computer. The comparison of radionuclide and radiographic contrast EFrn showed a high correlation ( r = 0.84) in 30 patients.
