Nitric oxide and its possible implication in ME/CFS (Part 2 of 2)
Andrew Gladman explores the current and historic hypotheses relating to nitric oxide problems in ME/CFS. This second article in a 2-Part series puts nitric oxide under the microscope and explores what it is, what it does and why it is so frequently discussed in the world of ME/CFS....

SPECT, PET, and CT, which brain scans reveal more?

    Hi,

    I had EEG done and it didn't show what's wrong neurologically. Which one of the other tests has more of a diagnostic value to it and I should go for as long as my insurance covers it. To my knowledge now PET seems to be one of the more modern options, but is also very expensive, it shows metabolism, SPECT is as I understand for oxygen flow and CT I didn't read alot about yet, which one is most recommended if you had to chose? And also could that contrast radioactive stuff they inject do even more damage to health?

    I'll answer myself PET probably is the better option but spect is also good and often does show brain pathology in CFS ME.

    I think it may be likely to be individual.

    Any of those tests have a potential to show something wrong in people like us (CT scan most unlikely: MRI, PET scan, EEG, and SPECT more likely), but it probably varies which test would show up something interesting. Also it may be that certain techniques are required (I don't know if anything special is needed in EEG).

    It also depends on who is reading the images. Some radiologists will sometimes miss something very significant, and some will miss something that is more unusual or more subtle, such as something that is out of place due to age (but might be "normal" in an older patient, such as the small spots we might have on MRI).
