Three dimensional pseudo-continuous arterial spin
labeling(3D pCASL) is able to differentiate delay
arrived blood flow form leptomeaningeal collaterals in
patients with middle cerebral artery stenosis by
applying multiple post labeling delay(PLD). We compared
multi-PLD 3D pCASL with conventional angiography
capillary index score(CIS) system in leptomeaningeal
collaterals assessment.
