We evaluated the feasibility of a spin echo (SE) EPI technique for MR perfusion imaging of moyamoya disease (MMD) on 3.0T MR system. Most MR perfusion techniques used a gradient echo EPI sequence due to a high sensitivity and broader coverage. A SE EPI, however, known to be sensitive to capillary vessels, but less to susceptibility, would be more useful in MMD with collaterals. Our preliminary results suggest a SE EPI sequence on 3.0 T MR provide high SNRs enough for the good quality perfusion map images and the hemodynamic information on MMD in accordance with the results of angiography.
