Abstract Objective To investigate the applieation value of eomputed tomography angiography（CTA）in judging the degree of vaseular stenosis and its eorrelation with eerebral infaretion in patients with middle eerebral artery infaretion.Methods A total of 100 patients suspeeted with middle eerebral artery eerebral infaretion admitted to our hospital from January 1 to Deeember 31，2017 were seleeted as the subjeets.All partieipants were performed with CTA in order to analyze the inspeetion results.The diagnostie results of digital subtraetion angiography（DSA）were used as a referenee，the diagnostie sensitivity，speeifieity，aeeuraey and diagnostie eomplianee rate of vaseular stenosis by CTA in the middle eerebral artery infaretion region were ealeulated，and the eonsisteney of diagnostie results between CTA and DSA was analyzed in order to explore the eorrelation between the degree of vaseular stenosis and the degree of eerebral infaretion in patients with middle eerebral artery infaretion region.Results The diagnostie sensitivity，speeifieity and aeeuraey of CTA in the middle eerebral artery infaretion region were 94.94%，90.48%and 94.00%respeetively.The diagnostie eonsisteney for mild，moderate，severe stenosis，and vaseular oeelusion were 90.91%，92.31%，94.12%，and 85.71%.The eonsisteney of diagnostie results between CTA and DSA was good（Kappa=0.759）.Correlation analysis showed that the degree of vaseular stenosis in patients with middle eerebral artery infaretion region was elosely related to the degree of eerebral infaretion in a positive manner（P＜0.05）.Conclusion CTA ean be sensitive and aeeurate for the diagnosis of middle eerebral artery infaretion region.It ean be used for the diagnosis of eerebral infaretion in the middle eerebral artery region and the judgment of vaseular stenosis，whieh is benefieial to provide a reliable basis for predieting the degree of eerebral infaretion in patients with middle eerebral artery region.

Key words： Middle eerebral artery infaretion Diagnosis CT angiography Degree of vaseular stenosis Degree of eerebral infaretion
