轮廓配准法在MRI评估健康成年人左心室心肌细胞外容积分数中的价值
Zhongshan Daxue xuebao. Yixue kexue ban, 2018 ： 【目的】探讨轮廓配准法在MRI纵向弛豫时间定量成像（T1 mapping）技术评估健康成年人左心室心 肌细胞外容积分数（ECV）中的价值。【方法】纳入26名健康志愿者（男16名，女10名），进行心脏MRI检查。采用 改良的Look-Locker 反转恢复（MOLLI）序列采集心底部、心室中部和心尖部三个短轴位对比增强前后的图像。 利用后处理软件通过常规法和配准法分别生成心肌ECV图并比较图像质量。将每个短轴位层面的图像分为形 变组和对照组，比较各层面及各组的常规ECV值和配准ECV值。【结果】
