Myocardial tissue characterization via quantitative T1 and T2 mapping is typically accomplished using ECG-triggering and breath-holding. Here we describe a novel method for non-ECG, free-breathing joint T1-T2 mapping using the cardiovascular low-rank tensor imaging framework for CMR multitasking. This method achieves joint T1-T2 mapping in the myocardium at multiple cardiac and respiratory phases within 1.5 min for one slice. Measurements were within the range reported in the literature, and were repeatable to 3.9% for T1 and 6.1% for T2.
