First-pass myocardial perfusion MRI is a promising technique for assessing ischemic heart diseases. 3D whole-heart coverage per heartbeat is desirable to overcome the volumetric coverage limitations of multislice 2D techniques. Highly accelerated imaging is required to reduce the long acquisition time per heartbeat of 3D perfusion MRI scans. In this work, we combine compressed sensing, parallel imaging and partial Fourier imaging to enable previously inaccessible accelerations. We demonstrate feasibility of whole-heart 3D perfusion MRI with 24-fold acceleration using the combined approach.
