Table 4 Summary of imaging results across the 2 groups of ataxic patients (MSA-C, SAOA) and healthy control subjects. One-way ANOVA did not demonstrate a significant difference in Cho/Cr from the hemisphere, so post hoc testing was not preformed
From: Is 1H-MR spectroscopy useful as a diagnostic aid in MSA-C?
