Fig. 1 Typical TCS findings in WD patient with corresponding MRI images using the fusion imaging technique. A) axial mesencephalic plane showing normal echogenicity of a substantita nigra; B) axial thalamic plane showing hyperechogenic lentiform nucleus. Numbers indicate following anatomical structures: 1 – mesencephalon; 2 – temporal lobe; 3 – cerebellum; 4 – third ventricle; 5 – frontal horn of lateral ventricle; 6 – caudate nucleus; 7 – lentiform nucleus; 8 – insula; 9 – occipital horn of lateral ventricle.

Fig. 2 Echogenicity index in A) substantia nigra (SN) and B) lentiform nucleus (NL) in control subjects, Wilson disease (WD) and early-onset Parkinson's disease (EO-PD) groups. Y-axes are differently adjusted for SN and NL values respectively. Echogenicity index in CN exhibited similar pattern as in NL and is thus not depicted in this graph.
