A variable refocusing flip-angle method is described for 2D Single-Shot Fast Spin Echo (SSFSE) for fast imaging of the brain and spine, which can be beneficial in pediatric populations to avoid sedation and repeated CT exams. The scheme allows for full-Fourier k-space acquisitions with improved sharpness and T2 contrast, and faster imaging compared with conventional SSFSE.
