Abstract：Objective To explore the value of dual source CT angiography (CTA) to the diagnosis of intracranial aneurysms. Methods DSA and dual source CTA were performed in 40 patients with subarachnoid hemorrhage (SAH), respectively. The number, size, location and morphology of the intracranial aneurysms detected by both the methods were analyzed. The detection rates of internal the aneurysms lacerum segment (C3), the cavernous segment (C4) and the clinoidal segment (C5) were compared between both the methods. Results A total of 44 aneurysms were detected by dual source CTA and DSA in 40 patients with SAH, respectively. The intracranial aneurysms, intracranial microaneurysms and internal carotid artery C3~C5 segments aneurysms detection rates of DSA and dual source CTA were both 100%. The sizes of long axes, short axes and necks of aneurysms detected by dual source CTA were insignificantly different from those detected by DSA (P>0.05). Conclusions Dual source CTA is a fast, simple, accurate and practical method to diagnose intracranial aneurysms, and dual source CTA examination, to a certain extent, can replace the DSA examination in the patients with intracranial aneurysms.
