Surgical management of convexity and falcine meningiomas using interactive image-guided surgery systems.

Interactive image-guided surgery systems can provide useful navigation information to assist craniotomy for meningiomas of the convexity and falx. When using MR imaging for navigation, interactive image-guided surgery can provide visualization of the relationship of tumor to venous anatomy, which may reduce the risk of debilitating infarction. Cortical surface anatomy can also be assessed, helping to estimate risk to functionally expressive areas.
