ABSTRACT
Objective To study the application value of multislice spiral CT angiography (MSCTA)in diag-nosis of intracranial aneurysms.Methods MSCTA was used to diagnose intracranial aneurysms in 40 patients with subarachnoid hemorrhage.Subtraction angiography digital (DSA)was used as the gold standard to evaluate the sensi-tivity,specificity and accuracy of MSCTA for diagnosis of intracranial aneurysms.Results In 40 patients,34 aneu-rysms were detected in 32 patients and they were all confirmed by incarceration of aneurysm.The aneurysms were de-tected in 33 cases by MSCTA,and the aneurysms were 34.Most of them were single (31 cases),1 case was multiple and 1 case was false positive.DSA was detected in 32 patients with 34 aneurysms,but single in 30 cases and multiple in 2 cases.DSA as the gold standard,the sensitivity,specificity and accuracy of MSCTA in diagnosis of intracranial aneurysms were 100%,87.50% and 97.50% respectively.MSCTA detected aneurysm neck width 1.85 -4.33mm, average aneurysm neck width was (3.65 ±1.85)mm.DSA detected aneurysm neck width 1.52 -4.48mm,average aneurysm neck width was (3.41 ±1.96)mm.The average tumor neck width detected by the two methods had no sta-tistically significant difference (t =0.78,P >0.05).But from the minimum of the detection,DSA still had certain ad-vantages.Conclusion The sensitivity of MSCTA for intracranial aneurysms was high.It can be used as a method for surgical treatment of intracranial aneurysms,but it still can not completely replace the DSA.
