Answer

Neuroimaging is probably more helpful in excluding other diagnoses than in ruling in mercury toxicity. Nonetheless, magnetic resonance imaging (MRI) in cases of Minamata disease confirms the clinical and pathologic findings. Marked atrophy of the calcarine and parietal cortices, as well as the cerebellar folia, has been visualized. [84]
