The main cause of hemifacial spasm is neurovascular compression syndrome. It is very important to preoperative evaluate the relationship between nerve and responsible blood vessel and its compression site. High-resolution 3D MR cisternography techniques were used preoperatively to assess neurovascular anatomy in patients with neurovascular compression syndrome, but the contrast between vessels and cranial nerves at the point of neurovascular contact is limited. In this study, we evaluated 3D VIBE image to could not only clearly show the structure of nerves and blood vessels, but also improve the contrast between blood vessels and nerves or surrounding brain stem.
