Acquisition Parameters for First-Pass ( FPRNA ) and Equilibrium Radionuclide Angiography ( ERNA )

Objective: Different methods are currently available to assess cardiac function, especially left ventricular ejection fraction, using either planar or tomographic imaging, firstpass or equilibrium techniques, and blood-pool or myocardial perfusion agents. This is the second article of a four-part series on nuclear cardiology. In this article the authors review the most widely used radiopharmaceuticals and methodologies.
