Measurement of Brain Trace Elements in a Dog with a Portosystemic Shunt: Relation between Hyperintensity on T1-Weighted Magnetic Resonance Images in Lentiform Nuclei and Brain Trace Elements.

Prior to euthanasia, brain magnetic resonance imaging (MRI) was performed for a five-year-old male Yorkshire Terrier following portosystemic shunt (PSS) surgical attenuation. Hyperintensity was observed on T1W images of the lentiform nuclei. Trace elements in this area were measured by inductively coupled plasma atomic emission spectrometry. The manganese concentration in the lentiform nuclei was four times higher than that in the control group. Therefore, the manganese accumulation would be the substance that causes the hyperintensity on T1W images of the lentiform nuclei in PSS dogs.
