最近对4个最广泛应用的T1定位序列的比较表明，反演恢复序列MOLLI20和ShMOLLI， 22具有更高的精度（即再现性），而SASHA24和SAPPHIRE26更准确（即更接近真实T1）。对比后T1时间的MOLLI序列的准确性可以通过使用不同的获取方案来提高，该方案占用更短的T1时间。该方案确保了大部分数据点定位在血液和心肌纵向松弛曲线的缩短上坡处。23对于血液T1测量，建议使用T1*。23日,28日
A recent comparison of the 4 most widely applied T1 mapping sequences demonstrated superior precision (ie, reproducibility) for the inversion recovery sequences MOLLI20 and ShMOLLI, 22 while SASHA24 and SAPPHIRE26 were more accurate (ie, closer to the true T1). 27 The accuracy of the MOLLI sequence for postcontrast T1 times can be improved by using a different acquisition scheme which accounts for shorter T1 times. This scheme ensures that the majority of data points are positioned into the shortened upslope of the longitudinal relaxation curves of blood and myocardium. 23 For blood T1 measurements, the use of T1* is recommended. 23, 28
