Contrast perfusion and arterial spin label (ASL) are the latest techniques available for quantitative hemodynamic analyses. The ASL MR imaging modality is becoming more clinically relevant, given the recent significant improvements in the high-field MRI. goal of this project is to help a better understanding of ASL as a noninvasive and non-radiation tool for perfusion territory measurements and predict the prospect of ASL as perfusion study at children and to compare rCBF difference between contrast perfusion MRI and ASL MRI at moyamoya disease. The ASL MRI technique at moyamoya disease shows a significant estimation of rCBF of PCA territory compared with enhanced perfusion MRI.
