You can measure other paramagnetic metals, too! Like iron and gadolinium

Elevated Mn levels were associated with welding fume exposure metrics and lower performance scores in motor tests.

In this cohort of welders, we show that the spatial distribution of excess brain Mn expands beyond the basal ganglia via white matter tracts to brain areas associated with motor and cognitive function.

Using whole-brain MRI relaxometry and statistical parametric mapping, we developed a novel method for depicting excess manganese (Mn) accumulation in the brain of welders.
