The … WebApr 3, 2014 · The quantitative differences between the MR volumes obtained by 2D- and 3D-proximal isovelocity surface area (PISA) were analyzed in various MR subgroups. In the validation cohort (n=52), MR volume obtained by 3D-PISA showed a better agreement with phase-contrast cardiac MRI than 2D-PISA ( r =0.97 versus 0.84).

WebAssuming a constant PV diameter in systole and diastole, a ratio of retrograde VTI (a measure of regurgitant volume) to antegrade VTI (a measure of total stroke volume) represents the regurgitant fraction.8 Theoretically, a ratio of 0.5 or more would indicate severe PR (i.e., a regurgitant fraction of ≥ 50%).
