To allow for T1 quantification in the presence of cardiac- and respiratory motion, an enhanced saturation recovery sequence is presented. EKG-triggering is employed to exclude cardiac motion, and respiratory navigator gating allows for data acquisition during free breathing. Thus, breath holding is not required, and T1 maps, e.g. of the myocardium, can be acquired with high spatial resolution, while patient comfort is improved substantially. First results were obtained in phantoms and in vivo.
