In this study, a 5.0T whole body MR imaging system was used for the evaluation of moyamoya disease (MMD). Diagnostic performance of time-of-flight magnetic resonance angiography (TOF-MRA) and susceptibility-weighted imaging (SWI) were evaluated and compared between the 5T MRI scanner and a clinical 3T MRI scanner in three MMD patients. Preliminary results show that 5 T MRI might be superior to 3T MRI for the visualization of small collateral branches and micro bleeding points.
