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 directionally-encoded (3ch. 2D-cine-3dir.) PC MR velocity vector map could overcome such limitations. The aim of this study is to assess intra- and interobserver variability of diastolic parameters measured by 2D-cine-3dir. PC MR velocity vector map.

3ch. 2D-cine-3dir. PC MR velocity vector map is a highly reliable and reproducible method and could be used as a part of routine examination.
