Abstract

Background: Approximately 10% of patients clinically diagnosed with early Parkinson's disease (PD) subsequently have normal dopaminergic functional imaging. Transcranial sonography (TCS) has been shown to detect midbrain hyperechogenicity in approximately 90% of Parkinson's disease (PD) patients and 10% of the healthy population. The aim of this study was to investigate the prevalence of midbrain hyperechogenicity in patients with suspected parkinsonism and scans without evidence of dopaminergic deficit (SWEDD), in comparison to PD patients. Methods: TCS was performed in 14 patients with SWEDD and 19 PD patients. Results: There was a significantly increased area of echogenicity in the PD group (0.24 ± 0.06 cm²), compared to the group of patients with SWEDD (0.13 ± 0.06 cm²; P < 0.001). One (9.1%) of these patients, compared to 14 (82.5%) of the PD patients, was found to have hyperechogenicity (P < 0.001). Conclusions: We conclude that TCS is useful to distinguish PD patients from patients with suspected parkinsonism and SWEDD.

<front><div type="abstract" xml:lang="en">Background: Approximately 10% of patients clinically diagnosed with early Parkinson's disease (PD) subsequently have normal dopaminergic functional imaging. Transcranial sonography (TCS) has been shown to detect midbrain hyperechogenicity in approximately 90% of Parkinson's disease (PD) patients and 10% of the healthy population. The aim of this study was to investigate the prevalence of midbrain hyperechogenicity in patients with suspected parkinsonism and scans without evidence of dopaminergic deficit (SWEDD), in comparison to PD patients. Methods: TCS was performed in 14 patients with SWEDD and 19 PD patients. Results: There was a significantly increased area of echogenicity in the PD group (0.24 ± 0.06 cm<sup>2</sup>
), compared to the group of patients with SWEDD (0.13 ± 0.06 cm<sup>2</sup>
; P < 0.001). One (9.1%) of these patients, compared to 14 (82.5%) of the PD patients, was found to have hyperechogenicity (P < 0.001). Conclusions: We conclude that TCS is useful to distinguish PD patients from patients with suspected parkinsonism and SWEDD.</div>
