Giving an example of high coverage cardiac perfusion MRI, we demonstrate how reformulating MS-CAIPIRINHA as a pure in-plane acceleration problem facilitates the integration of MS-CAIPIRINHA into the clinical workflow. By employing the multi-band excitation with phase oversampling in the imaging protocol, the multi-band acceleration problem reduces to a simple in-plane acceleration problem. Consequently the standard inbuilt parallel imaging functionality can be used for accelerating the measurement and reconstructing the images. This in turn renders mayor modifications to the sequence and the reconstruction chain unnecessary and provides the flexibility to attach available post-processing functionality like motion correction and up-slope map calculation.
