Are there any kinds of brain or nerve/ear tumours that a non contrast mri would miss?

Dr. Eric Weisman answered

Specializes in Neurology

Acoustic Neuroma: Hard to see until the get to be a certain size. Brainstem Auditory Evoked Potential Testing can detect the problem months to years before the tumor is visible on MRI. It is sensitive but not specific.
