Overview
Gadolinium-enhanced MRI scan is the definitive diagnostic test for acoustic neuroma and can identify tumors as small as 1-2 millimeter in diameter. On brain MRI, acoustic neuroma characterized by hypointense mass on T1-weighted MRI, and hyperintense mass on T2-weighted MRI.
MRI
- Gadolinium-enhanced magnetic resonance imaging (MRI) is the preferred diagnostic test for identifying acoustic neuromas and can identify tumors as small as 1-2 millimeter in diameter.[1][2]

Post-op MRI: Linear enhancement may not indicate tumor, but if there is nodular enhancement suspect tumor recurrence (needs follow up MRI).[3]
