Cardiac relaxometry techniques, particularly T1 mapping, have recently gained clinical importance in various cardiac pathologies. Myocardial T1 and extracellular volume are usually calculated from manual identification of left ventricular epicardial and endocardial regions. This is a laborious process, particularly for large volume studies. Here we present a fully automated relaxometry framework (FASTR) for segmental analysis of T1 maps (both native and postcontrast) and partition coefficient (λ).

技术说明：全自动分段弛豫法（FASTR）用于心脏磁共振T1定位

心脏弛豫测量技术，尤其是T1作图，最近在各种心脏病理学中已获得临床重要性。心肌T1和细胞外体积通常是通过手动识别左心室心外膜和心内膜区域来计算的。这是一个费力的过程，特别是对于大量研究而言。在这里，我们介绍了一个全自动的弛豫测量框架（FASTR），用于对T1图（本机和对比后）和分配系数（λ）进行分段分析。
