A whole heart perfusion imaging with auto-calibrated multiband CAIPIRINHA with through-time encoding and iterative reconstruction (tMB+CS-FPP) has been proposed to acquire multiple slices simultaneously without extra reference scans. The technique can achieve perfusion images with doubled anatomic coverage with identical spatial resolution. In this study, we compared the performance of the tMB+CS-FPP using different k-t undersampling patterns in a phantom study. And the proposed method was performed to the patients with suspect CAD and was compared to the conventional FPP.
