T1 mapping是一种新的磁共振技术，可直接测量心肌组织的T1值，从而评估心肌局部及弥漫性病变。 T1 map-ping具有多种扫描序列，如LL序列、MOLLI序列及ShMOLLI序列等。 T1 mapping分为平扫T1 mapping和增强T1 mapping ，另外，通过平扫T1值及增强T1值的测定，还可以计算得到心肌细胞外容积（extracellular volume， ECV），在评估心肌细胞水肿及心肌纤维化方面具有较大的临床价值。文中对心肌磁共振T1 mapping的扫描序列、技术方法及其临床应用进行综述。

T1 mapping is a new magnetic resonance imaging technique .By which the longitudinal relaxation time constant ( T1) of the myocardium can be measured to detect and quantitatively assess various focal or diffuse diseases .T1 mapping has various scan sequences , such as LL sequence , MOLLI sequence and ShMOLLI sequence .T1 mapping can be classified into two groups:pre--contrast and post-contrast T1 mapping.In addition, by measuring post-contrast T1 mapping and pre-contrast T1 mapping, myocardial extra-cellular volume (ECV) can be derived, which has been applied to assess myocardial edema and myocardial fibrosis with great clinical value .This review focuses on the techniques , methods and clinical application of cardiac magnetic resonance T 1 mapping technology .
