There are many causes of basal ganglia T1 hyperintensity, but the majority relate to deposition of T1-shortening elements within the basal ganglia such as:

calcium
- idiopathic calcification
- calcium and phosphate abnormalities
hepatic dysfunction or bypass (specifically affecting globi pallidi)
- acquired non-Wilsonian hepatocerebral degeneration
- Wilson disease (copper)
- hepatic encephalopathy
- hereditary hemorrhagic telangiectasia, often with hepatic arteriovenous malformations ⁵
toxins/ischemia
- carbon monoxide (usually low T1 signal; unless associated with hemorrhage)
- manganism
- non-ketotic hyperglycemic hemichorea ²
- kratom ⁶
- previous administration of linear gadolinium chelates ^3,4
- global hypoxia
blood
- methemoglobin in intracranial hemorrhage
- hemorrhagic infarct
others
- Japanese encephalitis
- hamartoma in neurofibromatosis type 1
- Fabry disease
