Quantitative cardiac volumes and measurements can be obtained for the left and right cardiac chambers and include the following 1-3:
- end-diastolic diameter
- interventricular septum thickness
- end-diastolic volume (EDV) [mL] and end-diastolic volume index (EDVI) [mL/m2]
- end-systolic volume (ESV) [mL] and end-systolic volume index (ESVI) [mL/m2]
- stroke volume [mL] and stroke volume index (SVI) [mL/m2]
- ejection fraction (EF) [%]
- cardiac output and cardiac index
- ventricular mass [g] and mass index [g/m2]*
- atrial volumes [mL] and atrial volume index [mL/m2]
Cardiac parameters derived from velocity-encoded imaging are typically obtained in the aorta and main pulmonary artery, but can be also obtained for the atrioventricular valves or atrial septal defects and ventricular septal defects:
- antegrade and retrograde flow volumes
- regurgitant fraction
- peak velocity
- mean velocity
