T2-weighted imaging typically employs either TSE or multi-pass 2D SE acquisitions, but using a thick slice and/or a slice gap is often necessary to overcome SNR inefficiencies of these methods, to achieve high-resolution scans in reasonable scan time. We studied efficient T2-weighted SE technique which employed localized quadratic encoding to realize SNR-efficient slice encoding scheme that produced contiguous volumetric coverage. Combined with long-readout spiral acquisitions, the proposed method, a hybrid of 2D and 3D imaging, demonstrated the expected SNR benefit compared to standard 2D scans and produced T2-weighted images with SNR equivalent as 2D-TSE scans but with larger, contiguous coverage.
