Magnetic resonance image and blood manganese concentration as indices for manganese content in the brain of rats
2000
Neurological disorders similar to parkinsonian syndrome and signal hyperintensity in brain on T1-weighted magnetic resonance (MR) images have been reported in patients receiving long-term total parenteral nutrition (TPN). These symptoms have been associated with manganese (Mn) depositions in brain. Although alterations of signal intensity on T1-weighted MR images in brain and of Mn concentration in blood are theoretically considered good indices for estimating Mn deposition in brain, precise correlations between these parameters have not been demonstrated as yet.
