Preliminary Study on the Application of Ultrahigh Field Magnetic Resonance in Moyamoya Disease

Figure 6

A 56-year-old male with weakness in the right limbs. The 7 T SWI sequence (b, c) showed a low signal area in the left basal ganglia region. The axial SWI sequence (d) showed an obvious brush sign in the semiovale region, especially in the left side. The SWI ((c) white arrow) sequences also showed ACVS in the left temporal parietal lobe. These findings suggested more severe ischemia in the left hemisphere.
