Axial T1

Coronal T2
Sagittal T1
Moderately dilated supratentorial ventricular system, with average-sized fourth ventricle. The degree of dilatation is disproportionate to the degree of sulcal effacement. The mamillopontine distance measures 11 mm.
High T2 signals are noted around the ventricles, reflecting periventricular permeation.
Narrow callosal angle measured on coronal images at the level of the posterior commissure. Normal floor of the 3rd ventricle.
Markedly widened Sylvian fissures.
Scattered white matter T2 hyperintensities mainly at the periventricular area and centrum semiovale, reflecting deep white matter ischemic changes.
