摘　　要：随着心脏磁共振成像技术的不断发展,T1 mapping可以无创性、可视化和定量地评估心脏疾病的心肌纤维化、水肿和浸润性。应用T1 mapping评估心肌疾病的局限性和弥漫性心肌纤维化,在疾病的诊断、鉴别、治疗和预后风险评估中发挥了重要的临床作用。本文旨在全面介绍T1 mapping在心肌病患者中的临床应用,归纳常用的扫描技术及其成像原理。As cardiac magnetic resonance imaging technology advances,T1 mapping has emerged as a non-invasive method offering visual and quantitative insights into myocardial fibrosis,edema,and infiltration associated with cardiac diseases.The application of T1 mapping in myocardial diseases allows for evaluating both focal and diffuse myocardial fibrosis,playing a crucial clinical role in the differentiation,treatment,and prognostic risk assessment of diseases.This article aims to provide a thorough overview of the clinical applications of T1 mapping in patients with cardiomyopathy,summarizing the commonly employed scanning techniques and imaging principles.
