Fig. 2

Representative images of cerebellar atrophy (T1-weighted image) and Vdx (a-d). Vdx is the cerebellar volume index (Vdx = cerebellar volume/cranial AP diameter). The mean Vdx value in normal adults (mean age, 64.2 ± 18.7 years; cranial AP diameter, 18.2 ± 1.1 cm) is 0.65 ± 0.06 cm3/mm. Vdx can be used to quantify the decrease in volume due to cerebellar atrophy, which is difficult to evaluate with visual qualitative assessment alone
