Mri for headaches/dizziness. Report says probable minimal clouding of the mastoid air cells bilaterally. My doctor just said MRI was normal.  Is it?

Probably yes: Mris of brain frequently demonstrate non-specific changes in the mastoid air cells. The literature demonstrates that as high as 40 to 50% of mris of the head detect false positive changes in the mastoid air cells. A cat scan is the appropriate radiological test to detect mastoid and middle ear disease. Finally, if your hearing is normal and there is no drainage, mastoid films are not needed. ...Read more
