Acceleration of rodent brain functional MRI using parallel imaging techniques is not widely used due to the limited availability of high-density phased-array coil on pre-clinical scanners. In this study we demonstrated a POMP-EPI method to enable simultaneous multi-slice acquisition for fast mouse brain imaging without a phased array coil. A four-fold multiband acceleration was achieved without using coil sensitivity information. This method can be used to increase the spatial or temporal resolution of mouse fMRI acquisition, which will benefit the study of dynamics of neural activity and connectivity.
