Synopsis

Keywords: Myocardium, CardiomyopathyThis study evaluated a cardiac T1ρdispersion mapping technique, termed as myocardial fibrosis index (mFI), to distinguish cardiac amyloidosis (CA) from hypertrophic cardiomyopathy (HCM). Our data showed that mFI is significantly superior to native T1 and contrasts medium-derived extracellular volume in the differential diagnosis of CA and HCM.
