Conventional cardiovascular MR (CMR) exams are relatively inefficient and demanding for patients because 1) they rely on methods that necessitate breath-holding or intermittent pauses (via gating) to compensate for motion, 2) images are acquired as a series of 2D slices often with large gaps. We propose a single 3D free-breathing acquisition without ECG requirements, providing motion resolved, quantitative T1 and T2 cine mapping with whole-ventricle coverage with high resolution and no slice gaps. The 3D Multitasking framework additionally incorporates a B1+ component, critical for accurate T1 measurement at 3T. This technique is preliminarily validated both in phantoms and healthy volunteers.
