2D Cartesian turbo spin-echo (TSE) is widely used in the clinical neuroimaging, yet the high specific absorption rate (SAR) induced by a large number of refocusing RF pulses limits its use in high magnetic field. Thus, this study describes a new TSE sequence with annular spiral ring acquisitions, dubbed “SPRING TSE”, for fast T2-weigthed imaging and reducing SAR. Preliminary results show that two sets of high spatial resolution images with intermediate and strong T2-weighted contrast characteristics can be obtained by the proposed method within a few seconds.
