SLC6A3 and bilateral striopallidodentate calcinosis: In addition to dopamine transporter single photon emission computed tomography (SPECT) using 123I-ioflupane, we examined 123I-metaiodobenzylguanidine (MIBG) scintigraphy that is useful to differentiate Lewy body-related disorders from other neurodegenerative disorders in genetically confirmed PFBC patients with parkinsonism20–23.
