In this study, we developed a 2D combined myocardial T1 and T2 mapping sequence that uses a combination of saturation pulse and T2 preparation pulse and allows simultaneously obtaining T1 and T2 map with acceptable breath holding time (12 heartbeats). High quality multiple T1 and T2 weighted images were obtained in the other cardiac cycle between the saturation pulse and T2 preparation pulse. Phantom experiment showed that T1 and T2 measured by proposed method highly correlated with reference methods. In vivo experiment showed that the proposed sequence can yield comparable myocardium T1 and T2 values with the conventional separated T1 and T2 mapping sequences.
