Abstract
Objective To investigate the clinical application of CT perfusion and angiography in acute cerebral infarction . Methods A total of 69 patients with acute cerebral infarction were enrolled in the hospital from May 2015 to June 2016 ,and trea-ted with CT perfusion and angiography detection respectively ,plain and perfusion imaging performance were analyzed .Ischemic ar-ea and cerebral blood flow parameters and its contralateral corresponding regional perfusion parameters were also compared ,and reconstruction of intracranial arterial and cervical angiographic images were analyzed .Results (1) Among the 69 patients with a-cute cerebral infarction ,skull plain showed that 41 cases had signs of early cerebral infarction ,and the other 28 cases had no abnor-mal perfusion area .CT perfusion imaging showed that the blood flow and cerebral blood volume in the cerebral infarction area were significantly lower than those in the contralateral imaging area ,and the difference of blood flow in the contralateral area was statis-tically significant (P<0.01) ,and the difference of cerebral blood volume was not statistically significant (P>0.05) .(2) The peak time of the contrast agent and the average passage time of the contrast agent in the cerebral infarction area were significantly longer than those in the contralateral imaging area (P<0.01) .(3) Angiography reconstruction results showed that 37 patients with unilateral internal carotid artery stenosis ,16 patients with unilateral cerebral artery stenosis ,11 patients with left cerebral ar-tery occlusion and 5 patients with left internal carotid artery occlusion .Conclusion CT perfusion can accurately and timely respond to the degree of cerebral ischemia and ischemic position of the patients ,and predict the penumbra ;CTA can discern the abnormal blood supply artery and the location effectively ,then provide important indicators for acute cerebral infarction patients .CT brain perfusion combined with blood vessels angiographic method is helpful for the early and accurate diagnosis of acute cerebral infarc-tion .关键词
