Idiopathic basal ganglia calcification CT and MRI scans

CT and MRI scans of a 75-year-old woman with IBGC involving the basal ganglia (A to C), subcortical white matter, and cerebellar dentate nucleus (D to F). CT (A, D) most clearly demonstrates calcifications, which are not as visible on T1 MRI sequence (C, F), but more apparent on GRE MRI sequence (C, F). Courtesy of Dr. Brent Weinberg.
