Background. Myocardial microscopic fibrosis (MF) may occur during systemic sclerosis (SSc) and lead to impaired myocardial contraction and/or arrhythmia. Cardiac magnetic resonance imaging (MRI) is used for the noninvasive characterization of myocardium. The aim of this study is to evaluate the impact of CMRI with diffusion-weighted imaging (DWI) andT1 mapping sequences to assess perfusion defect and myocardial MF, respectively.
