We present a radial Single-Shot Fast Spin Echo pulse sequence that is capable of generating multiple contrasts from a single spin echo train via temporal filtering. Undersampling artifacts are minimized by using a long echo train and an aggressive variable refocusing flip angle scheme. In vivo feasibility is demonstrated in the brain.
