title: Interventional equilibrium in blood pool studies.
abstract: Equilibrium gated studies ( MUGA studies) have come into widespread clinical use over the last several years. The accuracy of these studies in determination of ejection fraction and wall motion as compared with cardiac catheterization has proven to be quite favorable. Initially, only resting gated blood pool studies were performed. The measurement of ejection fraction and wall motion at rest is valuable; however, interventional ventriculography in the catheterization laboratory has become popular over the last several years. In view of the steady-state nature of the multi-gated study, it has been possible to adapt some of the interventions from the catheterization laboratory, especially stress and drug interventions, for use with the multi-gated studies. This article will discuss the technique and utility of these different procedures and indications for performance of interventional equilibrium gated studies.
