Clinical value of multi-slice spiral CT angiography in the diagnosis of intracranial aneurysms

Objective To investigate the clinical value of multi-slice spiral CT angiography(CTA) in the diagnosis of intracranial cerebral aneurysms. Methods From January 2014 to December 2016, the clinical data of 60 patients with suspected intracranial aneurysms in Yiwu Central Hospital were retrospectively analyzed.The patients received CTA, digital subtraction angiography(DSA) examination.Based on the postoperative pathological results, the specificity, accuracy, consistency of CTA and DSA in the diagnosis of intracranial aneurysm were calculated.CTA, DSA diagnosis results and cerebral aneurysm surgery results were analyzed.The intracranial aneurysm diameter, the maximum diameter of the aneurysm neck of CTA, DSA inspection were compared. Results Based on the postoperative pathological results, the diagnostic sensitivity, specificity and accuracy of CTA for intracranial aneurysms were 97.06%, 92.31%, 95.00%, respectively, which of DSA were 94.12%, 96.15%, 95.00%, respectively, there were no statistically significant differences between the two groups(all P>0.05). The consistency coefficient of CTA was 0.719, and DSA coefficient of agreement with the findings in operation was 0.736, the consistency was good.The intracranial artery tumor maximum diameter, maximum diameter of aneurysm neck by CTA, DSA examination had no statistically significant differences(all P>0.05). Conclusion CTA in the diagnosis of intracranial aneurysm has high sensitivity and accuracy, the diagnostic value is close to DSA and can be used as auxiliary means of DSA.
