This study was conducted to investigate the usefulness of PASL image technique through visual and quantitative assessment by dividing CBF image, conventional perfusion magnetic resonance image, anterior cerebral artery, middle cerebral artery and posterior cerebral artery into 6 territories both right and left in moyamoya disease. In visual assessment, the scope of decreased perfusion in the PASL CBF image and conventional perfusion MR CBF image agreed with the position of deficiency in the MR image. The quantitative assessment, showed that the scope and position of decreased perfusion accord with both in the PASL CBF image and the existing conventional perfusion MR CBF image but the assessment of measuring the quantity of perfusion according to signal intensity showed a little difference.

The authors reviewed the recent trend of surgical treatment for pediatric as well as adult onset moyamoya disease(MMD). Combined direct and indirect arterial anastomosis or multiple indirect arterial bypasss has been increasing for pediatric MMD and direct arterial bypass is recommended for adult MMD, especially in patients with hemorrhagic MMD. Besides perioperative complications related to the management of MMD and 1999 annual report by the Research Committee on Spontaneous Occlusion of the Circle of Willis(Moyamoya Disease) of the Ministry of Health and Welfare, Japan will be summarizd.
