Response Prediction after Gamma Knife Surgery (GKS) in Patients with Vestibular Schwannoma using Dynamic Contrast-Enhanced (DCE) MR Imaging
Condition or disease
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 .

Ages Eligible for Study:
20 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Patients with vestibular schwannoma, who underwent gamma knife surgery
Patients with vestibular schwannoma, who underwent gamma knife surgery and pre-op dynamic contrast enhanced (DCE) MRI
