*add new title – Brain axonal pathways revealed by DTI imaging

Lacunar infarctions are small subcortical infarcts, <1.5 cm in diameter, within deep areas of the brain

The cerebellum is supplied with blood via three branches of the basilar artery – the posterior inferior cerebellar artery (PICA), the anterior inferior cerebellar artery (AICA), and the superior cerebellar artery (SCA).

The image shows how the blood supply of the brain is arranged.
