Does velocity-encoded cine MR imaging provide reproducible and accurate measurements of regurgitant volume and fraction in patients with chronic aortic regurgitation?
Effect estimate: r > 0.97
Velocity-encoded cine MR imaging is highly accurate and reproducible for quantifying regurgitant volume and fraction in chronic aortic regurgitation, supporting its potential for serial monitoring.
Dulce et al. (1992) conducted an observational in Chronic aortic regurgitation (n=10). Velocity-encoded cine (VEC) magnetic resonance (MR) imaging vs. Volumetric measurements was evaluated on Interstudy reproducibility and correlation with volumetric measurements for regurgitant volume (RV) and regurgitant fraction (RF) (r > 0.97). Velocity-encoded cine MR imaging demonstrated high interstudy reproducibility (r > 0.97) for quantifying regurgitant volume and fraction in patients with chronic aortic regurgitation.
