Abstract：Dilated cardiomyopathy(DCM)is a highly heterogeneous cardiac disorder with complex etiologies.This review systematically explores the applications value of cardiovascular magnetic resonance(CMR)in pediatric DCM,including its advantages in etiological diagnosis,myocardial assessment,treatment effect monitoring,and prognostic judgment.Basic CMR sequences in DCM include cine sequences,black-blood sequences,and late gadolinium enhancement.Other sequences include T1 mapping,T2 mapping,extracellular volume fraction,and myocardial perfusion imaging.CMR also demonstrates significant value in evaluating right ventricular function,myocardial strain analysis,and intraventricular pressure gradient measurement.Meanwhile,this paper summarizes the CMR phenotypic features of specific genetic subtypes of DCM and describe challenges in applying CMR in pediatric patients and the strategies to deal with them,which provides robust support for clinicians to optimize diagnosis and personalized treatment approaches.
