Images obtained by cerebral PET scanning (e.g. PET/CT or PET/MRI) allow the non-invasive assessment of the binding capacity of the cerebral D2 dopamine receptor, which can be useful for the diagnosis of movement disorders.

[3] Other studies have investigated the relationship of D2 receptor binding capacity and personality disorders.

One study found decreased binding in the detachment personality trait.

[4] Radiolabelled raclopride is also commonly used to determine the efficacy and neurotoxicity of dopaminergic drugs.
