A role of basal moyamoya networks on cerebral circulation has not been clarified, mainly because of methodological limitation. The authors measured regional cerebral blood flow (rCBF) in 7 patients with moyamoya disease, by means of <SUP>133</SUP>Xe intracarotid injection method with reliable numbers of matrix as many as 87 and the following results were obtained.<BR>In 9 out of 10 sides in 7 cases, rCBF in the hemispheres and the white matters covering moyamoya vessels were significantly higher than those in the areas other than"the areas covering moyamoya vessels"although rCBF in the areas covering moyamoya vessels were still low compared to control. Therefore, it was concluded that basal moyamoya vessels played a significantly efficient role on maintenance of cerebral blood flow in the basal ganglionic areas and the white matters.
