Abstract

|
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.
