Sonographic images of mesencephalic and thalamic planes across study groups. Footnote: The figure shows ultrasound images of participants. Top row: raw images of the mesencephalic plane from patients with DLB, PD, AD and controls. Middle row: images of the mesencephalic plane, showing the perimeter of the mesencephalon (white external line) with the substantia nigra (SN) encircled (white internal line, black arrows). Bottom row: images of the thalamic plane, showing the size of the third ventricle (IIIv) (white line). The ultrasound findings include: SN hyperechogenicity and enlarged IIIv in a patient with DLB, SN hyperechogenicity with normal IIIv size in a patient with PD, normal echogenicity of the SN with enlarged IIIv in a patient with AD and normal SN echogenicity and normal IIIv size in a control subject
