Figure 3 The right vertebral artery V4 proximal dissection images of a 40-year-old female patient with dizziness and instable walking for 6 hours. (A) Is an MRA image. It can be seen that the vertebrobasilar artery minimum angle in this case is the basilar artery bending angle, which is measured to be approximately 75°. (B) Is a T1 VISTA scan image, showing eccentric crescent-shaped high signal at the proximal end of the right vertebral artery. (C) Shows no enhancement of vessel wall after T1 VISTA-enhancement. (D) Is an ASL image, and the right cerebellar hemisphere shows hypoperfusion.
