Abstract：Posterior circulation cerebral infarction has been paid close attention by clinicians. In some patients with posterior circulation cerebral infarction, the distribution of lesions does not match with the lesions of blood supply arteries, or the imaging of vascular stenosis does not match with clinical manifestations, indicating vascular anatomical variations or compensatory collateral circulation influences the cerebral blood supply, which plays an important role in the pathophysiological process of posterior circulation cerebral infarction. Posterior communicating artery is the most important collateral artery because it communicates the blood of posterior circulation and anterior circulation. The variation of posterior communicating artery influences blood flow compensatory, and is associated with the occurrence and outcome of in posterior circulation cerebral infarction. Medical imaging is an important means to evaluate posterior communicating artery. There are a variety of magnetic resonance angiography (MRA) techniques which can be used for the inspection of posterior communicating artery. In this paper, we summarized the inspection of posterior communicating artery using MRA and the studies of the relationship between posterior communicating artery and posterior circulation cerebral infarction to provide a reference for clinical screening the patients with potential high risk of the posterior circulation infarction using magnetic resonance angiography.
