摘　　要：心脏磁共振(Cardiovascular magnetic resonance,CMR)能“一站式”提供心脏形态、功能室壁运动情况、局部血流灌注及心肌活性等信息。纵向弛豫时间成像(T 1mapping)技术能量化人体组织每个体素的纵向弛豫时间常数(T 1),可以无创定量的评估心肌水肿与弥漫性心肌纤维化。近些年来,随着T 1mapping技术的发展,CMR已经成为心肌疾病诊断与治疗不可或缺的工具,具有重要的临床应用价值。Cardiovascular magnetic resonance(CMR)provides"one-stop"information on cardiac morphology,function,ventricular wall movement,local blood perfusion and myocardial activity.T 1 mapping can quantify the T_(1)valpe of each voxel in human tissues,and can noninvasively and quantitatively evaluate myocardial edema and diffuse myocardial fibrosis.In recent years,with the development of T_(1)mapping technology,CMR has become an indispensable tool for the diagnosis and treatment of cardiac diseases,with important clinical application value.
