Objective To explore the diagnostic value of three-dimensional spiral CT angiography(3D-CTA)technology in intracranial aneurysms.Methods Eighty suspected intracranial aneurysm patients who visited our hospital from August 2020 to June 2023 were included as the study subjects.All patients underwent 3D-CTA and digital subtraction angiography(DSA)examinations.Using DSA examination as the diagnostic gold standard,analyze the examination results,evaluate the diagnostic value of 3D-CTA in intracranial aneurysms,and calculate consistency;Compare the maximum diameter and neck diameter of intracranial aneurysms examined by 3D-CTA and DSA.Results After DSA examination,63 out of 80 suspected patients were ultimately confirmed to be positive for intracranial aneurysms(70 lesions),and 61 out of 68 lesions were confirmed to be intracranial aneurysms by 3D-CTA examination.The accuracy of 3D-CTA in the diagnosis of intracranial aneurysms 95%(76/80),specificity was 94%(16/17),sensitivity was 95%(60/63),negative predictive value was 84%(16/19),and positive predictive value was 98%(60/61).Consistency analysis showed that the diagnostic results of 3D-CTA were consistent with those of DSA(kappa value=0.857,P<0.001).There was no statistically significant difference(P＞0.05)between the two examinations in the comparison of the maximum diameter of the intracranial aneurysm body and the neck diameter.Conclusion The application value of 3D-CTA technology in the diagnosis of intracranial aneurysms is high,with high diagnostic accuracy and strong consistency with DSA.It can provide reliable reference for clinical diagnosis and treatment and is worth promoting and applying.
