Here we study SSFP-based OS-CMR and EPI-based T2*/T2 methods for detection of myocardial oxygenation changes. These techniques have been used previously, and OS-CMR has been investigated in many studies. However, quantifying T2* and T2 every heartbeat may add information to the semi-quantitative OS-CMR method. Here a limited study of subjects on a 3T scanner is performed. Preliminary quantitative results including comparisons between the methods are shown.
