Comparison of myocardial T_1-Mapping using real-time MRI and MOLLI at 1.5 Tesla

摘要

To compare myocardial T_1-mapping with real-time MRI~1 and the modified look-locker sequence MOLLI2. Subjects and Methods: The study was approved by local ethics committee. 20 volunteers (with written informed consent) without any history of cardiac diseases were examined at a 1.5 Tesla MRI. Acquisition parameters of the MOLLI sequence were: FOV = 380 9 380 mm~2, resolution = 1.5 × 1.5 × 8 mm~3, TE/TR = 1.10 ms/ 305.02 ms, FA = 35°, TA = 13.0 s. 8 images were acquired in order to fit a T_1 map.
