Percentage of patients with multiple system atrophy presenting with low fractional anisotropy or high apparent diffusion coefficient values without dorsolateral putaminal hyperintensity or hot cross bun signs
| ROI | Cut off points | MSA patients without DPH sign (n = 12) | MSA patients without HCB sign (n = 11) |
|---|---|---|---|
| ADC, apparent diffusion coefficient; DPH, dorsolateral putaminal hyperintensity; FA, fractional anisotropy; HCB, hot cross bun; MSA, multiple system atrophy; ROI, region of interest. | |||
