Fig. 6.

Appearance of basal ganglia T2*w hypointensities on T1w and T2w MRI. This figure shows the percentage of subjects with T2*w hypointensities in a specific basal ganglia or internal capsule region that appeared hypo-, iso- and hyperintense on T1w and T2w MRI. The anatomical structures include the caudate (C), putamen (P), globus pallidus (G) and internal capsule (I). There is a notable difference in appearance on T1w and T2w MRI between T2*w hypointensities in the globus pallidus and other structures. Globus pallidus T2*w hypointensities tend to appear hypo- and isointense on T1w and T2w MRI.
