  • Abstract
  • Look Inside

1. We evaluated the perivascular spaces (PVS) of the intraparenchymal arteries of the brain obtained from MRI, and compared them with the microangi- ograms of the injected autopsied brains of normal adults.

2. The three dimensional microangiograms revealed 3 types of intraparenchymal arteries : intracortical, subcortical (including arteries of arcuate fibers) and medullary arteries. PVS of those arteries had punc- tated or small linear-shaped appearances according to the dimension and level of MR slices.
