Answer

Brain magnetic resonance imaging (MRI): Particularly in cases of centrally mediated dysautonomia

In MSA, brainstem or cerebellar atrophy may be seen, with T2 hyperintensity of the pons (the hot-crossed bun sign); these findings differentiate MSA from other types of primary autonomic dysfunction. [4]

See Workup for more detail.
