Inclusion Criteria: * Patients with vestibular schwannoma, who underwent gamma knife surgery and pre-op dynamic contrast enhanced (DCE) MRI * Patients with vestibular schwannoma, who received consent Exclusion Criteria: * In addition to the vestibular schwannoma, if the brain has other underlying or systemic disease * During the observation period, other treatments were performed other than gamma knife surgery * If patients have a contraindication to MRI (eg, pacemaker, cochlear implants, hemodynamically unstable) * Concomitant use of gadolinium MRI contrast agents (eg, renal insufficiency \[glomerular filtration rate \<30 ML / min\]), or if there was a side effect when using a contrast medium. * Adults with impaired ability to cope * If the images and medical records required for this study are not available or are not appropriate
