Research progress of T1 mapping MRI in dilated cardiomyopathy
Dilated cardiomyopathy(DCM)is a common disease of the cardiovascular system with a strong family history of impaired systolic function caused by the expansion or enlargement of the ventricular cavity.Late gadolinium enhancement(LGE)can be widely used as an effective means for the diagnosis of noninvasive myocardial fibrosis,but its accuracy in the diagnosis of diffuse myocardial fibrosis is lacking,so it has certain limitations in clinical application.In recent years,the clinical application of T1 mapping technology has brought great changes to medical imaging,especially for the diagnosis,recognition and prognosis of diffuse myocardial fibrosis.It can detect T1 value and extracellular volume(ECV)with high accuracy.Conduct a comprehensive evaluation of DCM.This paper summarized the latest progress in the application of T1 mapping and ECV in the early diagnosis,identification of related diseases,risk stratification,prognosis assessment and therapeutic efficacy assessment of DCM patients,aiming to improve the early detection rate of DCM and make more accurate judgment on the progression of patients'disease,so as to formulate the best treatment strategy for patients.It is expected to improve the prognosis of patients and provide a reference direction for future research.
