In this study, a dual cine and 3D T1 mapping method using stack-of-spirals sampling scheme and a Look-Locker approach at high magnetic field is presented. This method has been tested on mice beating heart and allows to differentiate with a high contrast to noise ratio the blood and the myocardium. The dual quantification of T1 and cardiac cinematic might allows a precise characterization of tissue damages induced by a myocardial infarction.
