Associations between the magnetic transfer ratio indices and blood manganese levels. Correlations were tested with Pearson’s correlation coefficient
| MTR index normalised to WM | Pearson correlation coefficient | p Value | MTR index normalised to PU | Pearson correlation coefficient | p Value |
| Globus pallidus | −0.54 | 0.196 | Globus pallidus | −0.75 | 0.008 |
| Head of caudate | −0.11 | 0.720 | Head of caudate | −0.53 | 0.156 |
| Thalamus | 0.09 | 0.761 | Thalamus | −0.25 | 0.393 |
| Putamen | 0.58 | 0.087 | White matter | −0.58 | 0.087 |
MTR, magnetisation transfer ratio; PU, putamen; WM, white matter.
