Evaluation of new data processing algorithms for planar gated ventriculography (MUGA).

Before implementing one of two new LVEF radionuclide gated ventriculogram (MUGA) systems, the results from 315 consecutive parallel patient studies were evaluated. Each gamma-camera acquisition was simultaneously processed by semi-automatic Medasys Pinnacle and by fully-automatic and semi-automatic Philips nuclear medicine computer systems. The Philips systems yielded LVEF results within +/- 5 LVEF percentage points of the Medasys system in fewer than half of the studies.
