There's a myelogram and an encephalogram, sounds like maybe you're combining the two? Or maybe there's a closer term that I'm not familiar with.

Heard the name of this medical procedure in a couple of TV shows before. I am not 100% sure I have the word or it's spelling correct but I think I heard it pronounced phonetically as

"My-o-in-cep-leo-gram"

If someone can supply the correct version of this word with a definition as well that would be helpful.

Thank you.

[TOMT][Word] Name of a medical prodecure
