Non-invasive imaging of cardiac anatomy plays an important role in diagnosis, risk stratification, and planning of procedures in patients with cardiovascular disease. MR imaging has the potential to provide a comprehensive evaluation of cardiac chambers and thoracic vessels. However, the clinical workflow for the acquisition of conventional cardiac MR imaging is complex and time-consuming. MR MultiTasking based 3D Multi-dimensional Assessment of Cardiovascular System (MT-MACS) technique has recently been demonstrated in thoracic aortic diseases without need for ECG- and navigator-gating. In this work, we further extend the application of MT-MACS to the assessment of the whole heart and great thoracic vessels.
