Do They Need an MRI LP or an EEG?

The Holy Trinity of the neuro workup is an MRI and LP and EEG. "I think for anyone who doesn't come in with like, ultra mental status, in my mind deserves a head CT before they get a needle stuck in their back," says Dr. David Schulder. The next thing I really want to know in terms of like triaging, which of these is most important is whether or not they had a fever? So any, any clarity on that?
