NON-INVASIVE QUANTIFICATION OF CARDIAC OUTPUT WITH PHASE VELOCITY MAPPING IN PATIENTS WITH PULMONARY HYPERTENSION

Background: The use of the Fick principle and the thermodilution (TD) method via right heart catheterization (RHC) has remained the most reliable means of cardiac output (CO) measurement. Using CMR, phase velocity mapping (PVM) is a non-invasive, rapid, highly reproducible technique to measure CO.
