Abstract

Background One-directionally-encoded cine 2D Phase-Contrast MRI (PC MRI) of basal short axial image is generally used for the evaluation of diastolic function, but has potential limitations due to the longitudinal cardiac motion and inflow direction. Time-resolved 3D PC MRI is not affected by the flow direction and left ventricular motion, however, requires long acquisition time. In theory, three chamber view 2D cine three directionallyencoded (3ch. 2D-cine-3dir.) PC MR velocity vector map could overcome such limitations. The aim of this study is to assess intraand interobserver variability of diastolic parameters measured by 2D-cine-3dir. PC MR velocity vector map.

Intra- and interobserver variability were calculated by means of intraclass correlation coefficient (ICC (1,1) and ICC (2,1)) for the peak E and A velocity, Spearman’s rank correlation coefficient for E/A ratio, and Cohen’s kappa coefficient for inflow pattern
