TL;DR: Which imaging location (at, above, or below the aortic valve) on phase contrast MRI best correlates with echocardiography is determined.
Abstract: Introduction Echocardiography is the most widely used imaging modality for assessment of aortic regurgitation. Phase contrast MRI may also be used to quantify aortic regurgitation, but no standard imaging location has been identified on MRI. The purpose of this study is to determine which imaging location (at, above, or below the aortic valve) on phase contrast MRI best correlates with echocardiography.

TL;DR: This work demonstrates the pitfalls of solely magnitude based DE imaging for the simultaneous detection of intra-cardiac thrombus and shows the benefits of the PSIR technique by theoretical and clinical analysis.
Abstract: Introduction Late enhancement techniques have been recently used for the detection of intra-cardiac thrombus due to its characteristic appearance in DE images. For time reasons in clinical practice frequently a TI is chosen which nulls the normal myocardium and not the thrombus allowing simultaneous evaluation of myocardial scar and thrombus. This work demonstrates the pitfalls of solely magnitude based DE imaging for the simultaneous detection of intra-cardiac thrombus and shows the benefits of the PSIR technique by theoretical and clinical analysis
