Uremic cardiomyopathy is the adverse cardiac remodeling that commonly occurs in patients with chronic kidney disease. Previous studies have indicated increased intramyocardial fluid and myocardial fibrosis in uremic patients, which makes native myocardial T2 and T1ρ mapping ideal imaging biomarkers to characterize these changes. Therefore, we propose a free-breathing simultaneous T2 and T1ρ mapping technique to provide co-registered T2 and T1ρ maps. The proposed technique was firstly evaluated in phantoms and ten healthy subjects, which achieved similar performance to the conventional separate T2 and T1ρ mapping methods. The preliminary validation in four hemodialysis patients showed promising results.
