PURPOSE To compare the applicability of different self-gating (SG) strategies for respiratory SG in cardiac MRI in combination with iteratively reconstructed (k-t SPARSE SENSE) cine data with low and high temporal resolution. METHODS Eleven SG variants were compared in five volunteers by assessment of the resulting image sharpness compared with nongated… (More)
It is objective of this study to investigate the potential of velocity encoded MRI (TPM) to derive quantitative parameters based on local displacement information for the automatic assessment of mechanical asynchrony in CRT patients.
It is objective of this study to investigate the potential role of different automatically derived quantitative parameters derived from velocity encoded MRI for the identification of asynchronic patients.
It is objective to show the feasibility of volumetric velocity encoded MRI (3D-TPM) to derive velocity based motion quantification parameters.
BACKGROUND The objective of this study was the quantification of myocardial motion from 3D tissue phase mapped (TPM) CMR. Recent work on myocardial motion quantification by TPM has been focussed on multi-slice 2D acquisitions thus excluding motion information from large regions of the left ventricle. Volumetric motion assessment appears an important next… (More)
OBJECT Until now, a three-directional velocity field has mostly been obtained by velocity encoding in three directions, which is very time-consuming and hence not usually used in clinical routine. We show the feasibility of combining in-plane tagging with through-plane tissue phase mapping (TPM) to encode a three-directional velocity field at 3 T with… (More)
PURPOSE The combination of fully balanced SSFP sequences with iterative golden angle radial sparse parallel (iGRASP) MRI leads to strong image artifacts due to eddy currents caused by the large angular increment of the golden angle ordering. The purpose of this work is to enable the combination of iterative golden angle radial sparse parallel MRI with… (More)
