MR native T1 mapping technique was found have the ability of detecting diffuse myocardial fibrosis which was found in histological examination of dilated cardiomypathy (DCM). Texture analysis of T1 mapping had been proved to be able to provide more information besides T1 value. We found several histogram parameters (statistical class of texture analysis) were significantly higher in DCM than that of healthy volunteers. The areas under the receiver operating characteristic curve of histogram parameters were calculated. The results indicate that texture analysis of T1 mapping may be helpful for the diagnosis of DCM.
