Abstract Objective: To study the clinical application value of multislice spiral CT angiography(MSCTA) in the diagnosis of intracranial aneurysms. Methods: The MSCTA and DSA imaging data of 121 cases highly suspected of intracranial aneurysm were analysed retrospectively. All cases were comfirmed by surgical operation or interventional embolization. After treatment all cases were given MSCTA and DSA re-examinations. Result: In the 121 patients, 116 patients had intracranial aneurysm(altogether 124 aneurysms), while in 3 cases there were 3, 4 and 4 aneurysms respectively. MSCTA gave correct diagnosis in 121 aneurysms and misdiagnosed in 4 with a detection rate of 97.6%, DSA detected 123 aneurysms, misdiagnosed in 3 and 4 miss diagnosed. The detection rate of DSA was 96.7%. There was no significant difference of detection rate between the two examinations(P>0.05). Conclusion: MSCTA has minimal invasion, fast, accurate, with very few complications, and powerful post-processing capabilities. It is a method of choice for the diagnosis of intracranial aneurysms.
