We assessed diagnostic feasibility of vessel wall imaging with MSDE-prepared, 3D T1-weighted variable refocusing flip angle fast spin echo MR imaging (CUBE T1) in differentiation between moyamoya disease (MMD) and intracranial atherosclerotic disease (ICAD), both of which can cause stenosis of the intracranial arteries. MSDE-prepared CUBE T1 enabled correct differentiation in our cohorts and may be helpful to differentiate MMD from ICAD when luminal narrowing is found on conventional brain MRA.
