The basal gray matter in the cerebrum is supplied by different anatomical
groups of perforating arteries, including striate, thalamic, and choroidal
arteries. In this pictorial essay we illustrate multiplanar MR imaging of
infarctions in those regions and correlate their appearances with cerebral
angiographic findings of the same patients when available. We also
correlate the extent and location of infarctions on multiplanar MR images
with the anatomical distributions of perforating arteries seen on
microangiograms of unrelated cadavers. Information conveyed from this
correlation will increase understanding of patterns of basal cerebral
infarction shown on cross-sectional imaging.
