## Abstract Transcranial Doppler imaging (TCDI) has been used as a noninvasive diagnostic tool to differentiate Parkinson's disease (PD) from atypical parkinsonism by detecting hyperechogenicity in the substantia nigra (SN). To our knowledge, no TCDI data are available for Asian populations, and TC

## Abstract Increased echogenic size (hyperechogenicity) of the substantia nigra (SN) is a characteristic transcranial sonography finding in patients with Parkinson's disease (PD). The SN echogenic size does not change in the course of the disease. In order to see whether this stable ultrasound mar
