A stimulated echo is formed after three 90^o RF pulses. Magnetization-preparation is accomplished immediately after the first RF pulse and the second RF pulse restores a half of prepared magnetization into the longitudinal space. Other half is remained on the transverse plane. In the conventional stimulated-echo pulse sequence, a half of the prepared magnetization is discarded. A novel imaging technique has been developed to utilize other half of the prepared magnetization at the spin-echo position and simultaneously acquire spin-, gradient-, and stimulated-EPI in a singleshot using 2D singleshot spin-/stimulated-EPI (2D ss-SGSTEPI).
