Late gadolinium enhancement (LGE) is the widely used method to evaluate the myocardial fibrosis in various heart diseases. However, the standard LGE using null-point method has a limitation in diagnosis of diffuse interstitial fibrosis. This study demonstrated that pre-contrast and post-contrast myocardial T1 mapping using a faster MOLLI method enable direct myocardial signal quantification and can help to evaluate the diffuse fibrotic change even that show apparently unenhanced myocardium on LGE images, in patients with dilated cardiomyopathy (DCM).
