Flowchart of patient selection and the PD diagnostic accuracy of the combined use of cardiac MIBG scintigraphy, olfactory testing and transcranial sonography.
* A total of 88 patients were included in the analysis (51 patients were not assessable for SN echogenicity by transcranial sonography). SN+ = substantia nigra hyperechogenicity positive; MIBG+ = cardiac MIBG scintigraphy positive; OE+ = olfactory testing positive.
