Overview
Gadolinium-enhanced MRI scan is diagnostic of Acoutic neuroma. On brain MRI, glioblastoma is characterized by hypointense mass on T1-weighted MRI and hyperintense mass on T2-weighted MRI
MRI
Magnetic resonance imaging (MRI) using Gadolinium as an enhancing contrast material is the preferred diagnostic test for identifying acoustic neuromas. The image formed clearly defines an acoustic neuroma if it is present and this technique can identify tumors measuring only a few millimeters in diameter. Tumors as small as 1-2 mm in diameter can be demonstrated by well performed MRI scanning. Nonenhanced MRI can miss small tumors.[1]
