Myocardial perfusion MRI is a unique imaging technique that offers information about myocardial health due to narrowed/blocked coronary arteries. Fast imaging methods that undersample k-space and use advanced reconstruction methods like compressed sensing have led to increased slice coverage or increased spatial resolution over conventional methods without sacrificing temporal resolution. Feasibility of ungated perfusion imaging with these advanced methods was also shown recently. An ungated acquisition continuously acquires perfusion data ignoring ECG gating and is highly efficient in data collection compared to standard ECG gated acquisitions, especially in case of arrhythmias. Here we present a framework that is complementary to k-space undersampling methods to increase slice coverage by using a simultaneous multi-slice radial acquisition. Promising results are shown in-vivo combining CAIPI with radial undersampling and compressed sensing reconstructions.
