CMR在亚临床期糖尿病心肌病的应用进展

Advances in the Use of CMR in Subclinical Diabetic Cardiomyopathy

亚临床期糖尿病心肌病(DCM)主要表现为心肌纤维化、左心室肥厚和心肌舒张异常。心脏磁共振(CMR)技术可快速准确判断糖尿病患者的心肌结构及功能,对亚临床期DCM的早期诊断和预后评价起到至关重要的作用。评估亚临床期DCM的CMR技术主要包括心脏磁共振特征性追踪(CMR-FT)、心肌磁共振波谱成像(MRS)、T1mapping技术、磁共振心肌灌注成像等。本文对CMR技术在亚临床期糖尿病心肌病诊断中的研究进展进行综述。

Diabetic cardiomyopathy(DCM)presents as myocardial fibrosis,left ventricular hypertrophy,and myocardial diastolic abnormalities.Cardiac magnetic resonance(CMR)technology can quickly and accurately determine the myocardial structure and cardiac function of diabetic patients and plays a crucial role in the diagnostic and prognostic evaluation of subclinical DCM.Evaluation of subclinical DCM using CMR technology primarily involves cardiac magnetic resonance�feature tracking(CMR-FT),magnetic resonance spectroscopy(MRS),T1 mapping technology,and magnetic resonance myocardial perfusion imaging.This paper reviews the research progress of CMR technology in the diagnosis of subclinical diabetic cardiomyopathy.
