There is an overall drive to high resolution brain MRI with a short scan time. In this study, it was investigated whether 3D EPI fMRI scans acquired with high density receive arrays, can still benefit from a CAIPI sampling pattern, in terms of (temporal) SNR. A 2D CAIPIRINHA acceleration scheme for multi-shot 3D EPI scans was implemented. When combining this implementation with high density receive coil arrays at 7T, it allowed substantial reduction of the scan time for sub-millimeter fMRI scans of the visual cortex.
