Abstract
Cardiac magnetic resonance (CMR) imaging is widely used in various medical fields related to cardiovascular diseases. Rapid technological innovations in magnetic resonance imaging in recent times have resulted in the development of new techniques for CMR imaging. T1 and T2 image mapping sequences enable the direct quantification of T1, T2, and extracellular volume fraction (ECV) values of the myocardium, leading to the progressive integration of these sequences into routine CMR settings. Currently, T1, T2, and ECV values are being recognized as not only robust biomarkers for diagnosis of cardiomyopathies, but also predictive factors for treatment monitoring and prognosis. In this study, we have reviewed various T1 and T2 mapping sequence techniques and their clinical applications.
摘要
心脏磁共振成像（CMR）在与心血管疾病相关的各个医学领域中被广泛应用。近年来磁共振成像技术的快速创新推动了CMR成像新技术的发展。T1和T2图像映射序列能够直接定量心肌的T1、T2和细胞外容积分数（ECV）值，促使这些序列逐渐融入常规CMR检查中。目前，T1、T2和ECV值不仅被视为诊断心肌病的可靠生物标志物，也是治疗监测和预后的预测因素。在本研究中，我们综述了各种T1和T2映射序列技术及其临床应用。
