In
this study, we demonstrated the utility of intracranial MR angiography
(MRA) using acceleration-selective arterial spin labeling
(AccASL) technique in Moyamoya disease. The AccASL-MRA markedly
improved the visualization of arteries distal to the steno-occlusive site reflecting
collateral flow via LMA in Moyamoya disease in comparison with time-of-flight
(TOF)-MRA.
