Processing a Cardiac Planar Gated Bloodpool Study (MUGA)

Processing a Cardiac Planar Gated Bloodpool Study (MUGA) Description: The purpose of this step by step is to assist you in navigating the Planar Gated Bloodpool activity to calculate ejection fraction, display wall motion, and analyze cardiac volume curves. 1. Select the desired static or whole body series from the MI Apps Patient Browser and launch the MUGA processing workflow 2. Select the Gated Bloodpool activity and select the Processing tab. 3.
