Abstract

Myocardial T 1 mapping is a quantitative MRI technique that has found great clinical utility in the detection of various heart disease. These acquisitions typically require three breath-holds, leading to long scan durations and patient discomfort. Simultaneous multi-slice (SMS) imaging has been shown to reduce the scan time of myocardial T 1 mapping to a single breath-hold without sacrificing coverage, albeit at reduced precision. In this work, we propose a new reconstruction strategy for SMS imaging that combines the advantages of two different k-space interpolation strategies, while allowing for regularization, in order to improve the precision of accelerated mycordial T 1 mapping.

改进的正则化重建多层心脏MRI t1同步定位。
心肌t1定位是一种定量MRI技术,在各种心脏病的检测中具有很大的临床应用价值。这些采集通常需要三次屏气,导致扫描持续时间长,患者感到不适。同时多层(SMS)成像已被证明可以减少心肌t1映射到单次屏气的扫描时间,而不牺牲覆盖范围,尽管精度降低。在这项工作中,我们提出了一种新的SMS成像重建策略,该策略结合了两种不同k空间插值策略的优点,同时允许正则化,以提高加速mycordial t1映射的精度。
