256 Slice Spiral CT Head and Neck Angiography with Cerebral Perfusion in Acute Cerebral Infarction
Objective:To explore the clinical application value of CT cerebral perfusion and angiography in acute cerebral infarction.Methods:65 patients with acute cerebral infarction treated in our hospital from February 2022 to October 2023 were selected as the study subjects.All patients received CT cerebral perfusion and angiography,respectively,compare and analyze the parameters of the infarcted area and the healthy side.Results:In 65 patients,39 patients showed signs of early cerebral infarction,at 60.00%,the rest showed no perfusion abnormalities,CT cerebral perfusion showed,CBV in the infarct area(42.85±11.20)mL/(100g·min)and CBF(1.98±0.73)mL/100g were significantly lower than the healthy area(56.02±12.87)mL/(100g·min),(2.43±0.86)mL/100g(P<0.05),TTP(45.17±10.96)s and MTT(26.47±2.08)s in the infarct zone were significantly higher than in the healthy block(22.51±7.23)s,(4.01±1.52)(P<0.05).Angiographic results showed that the 65 patients in this group had 35 internal carotid artery stenosis,15 middle cerebral artery stenosis,5 carotid artery occlusion in one carotid artery and 10 occlusion in one side.Conclusion:CT perfusion has some advantages in the diagnosis can improve the diagnostic accuracy of acute cerebral infarction and provide favorable basis for further treatment.
