Abstract:
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 .
