"Hunter's angle is an angle made by the line connecting the metabolites: myo-inositol, choline, creatine, and N-acetyl aspartate (NAA) peaks in MR spectroscopy with the horizontal plane. If the angle roughly corresponded to the 45° angle, the curve was considered probably normal 1. If the peaks strayed off the comb's angle, the curve was abnormal 1,2. This is a quick and useful visual method to read MRS and determine normal from abnormal. It is important to remember, however, that this angle was used with STEAM spectra from the brain 3."
