Can magnetic resonance spectroscopy be used to detect lyme disease or other infections in the brain? if so how?

Spectroscopy uses: Typically MR spectroscopy (MRS) is a problem solver used to evaluate tiny volumes of tissue for signs of malignancy or to characterize MS. Infectious lesions can be investigated with MRS but MRS is not, in my experience, commonly used for this. There is one article where MRS was used for dx. of a brain virus, so yes someone might try to use it for Lyme, but I am not aware of an article yet.

Not a relevant test: NMR is not an appropriate investigative tool for diagnosing infections.
