The value of cardiac CT in diagnosis of coronary atherosclerotic heart disease has been established by numerous studies and endorsed by guidelines.However,the value of cardiac CT in cardiomyopathy is yet to be determined.With the advancement of CT technology,hardware and software of computer,cardiac CT has become a growing area of study in cardiomyopathy.In addition to evaluating cardiac anatomy and analyzing cardiac function,cardiac CT also analyses myocardial and epicardial adipose tissue.At present,various methods of cardiac CT are available for assessing cardiomyopathy such as delayed enhancement,extracellular volume,iodine map,myocardial perfusion,myocardial strain,and radiomics.This article reviews the research progress of the above methods in the diagnosis,treatment,and prognosis in cardiomyopathy.
