Brief Summary:
MR Fingerprinting (MRF) will be performed in patients who will be treated with Gamma Knife
radio surgery for a vestibular schwannoma before the intervention. Fifty patients will be
included with a vestibular schwannoma of minimum 1cm in size. During follow-up, response of
the tumor to radiosurgery will be evaluated for each patient with MRI. The aim of the study
is to find patterns of vestibular schwannomas in MRF data which correlate with the type of
response to radio surgery, i.e. tumor control after radiosurgery, further tumor growth
despite radiosurgery, cystic transformation after radiosurgery.
Inclusion Criteria: Planned Gamma Knife radiosurgery for vestibular schwannoma of minimum
1cm in size -
Exclusion Criteria: Vestibular Schwannoma of less than 1cm in size. Other a priori
treatment than Gamma Knife radiosurgery
-
Primary outcome:
1. Tumor control (Time Frame - 3 years):
Number of patients without further growth of the tumor on follow-up MRI after radiosurgery
2. Tumor growth (Time Frame - 3 years):
Number of patients with growth of the tumor on follow-up MRI after radiosurgery
3. Cystic transformation (Time Frame - 3 years):
Number of patients with cystic transformation of the tumor on follow-up MRI after radiosurgery
- MR Fingerprinting:
Specific Magnetic Resonance Imaging protocol
