Study Type: Observational
Official Title: Response Prediction After Gamma Knife Surgery (GKS) in Patients With Vestibular Schwannoma Using Dynamic Contrast-Enhanced (DCE) MR Imaging
Brief Summary: Response Prediction after Gamma Knife Surgery (GKS) in Patients with Vestibular Schwannoma using Dynamic Contrast-Enhanced (DCE) MR Imaging
Detailed Summary: The purpose of this study was to evaluate the response of Gamma Knife Surgery to Ktrans, Ve, and Vp, which are indicators of permeability map obtained from dynamic contrast enhanced (DCE) MRI in patients with vestibular schwannoma .
Sponsor: Seoul National University Hospital
Current Primary Outcome: Tumor size change before and after surgery [ Time Frame: pre-op, Immediately after surgery ]
Original Primary Outcome: Same as current
Current Secondary Outcome: In patients who underwent gamma knife surgery, the magnitude of tumor size change before and after surgery [ Time Frame: through study completion, an average of 1 year ]
Original Secondary Outcome: Same as current
