Title: Value of 3-dimensional multi-slice computed tomography angiography in the diagnosis of intracranial aneurysm
Abstract: Objective Eighty percent of subarachnoid hemorrhage is induced by ruptured intracranial aneurysm,and its mortality is as high as 50%.This article aims to evaluate 3-dimensional multi-slice computed tomography angiography(3D-MSCTA) in the diagnosis of intracranial aneurysm.Methods We retrospectively analyzed the 3D-MSCTA images of 42 cases of spontaneous subarachnoid hemorrhage(SAH) confirmed by digital subtraction angiography(DSA) and surgery.All the patients underwent CT scanning and enhanced CT scanning,followed by three-dimensional reconstruction of brain blood vessels using VR,MPR and MIP techniques.And observations were made by reference to the original images.Results Of the 42 patients,40 were diagnosed with 44 intracranial aneurysms by 3D-MSCTA,and 41 with 46 aneurysms by DSA.The detection rate of intracranial aneurysm by 3D-MSCTA was 95.7%.Conclusion 3D-MSCTA,non-invasive and highly sensitive,can be used as a safe and fast conventional screening method for the diagnosis of intracranial aneurysm,as well as for providing detailed information for its treatment protocol.Further examination by DSA can be performed if 3D-MSCTA fails to reveal intracranial aneurysm in patients with spontaneous subarachnoid hemorrhage.
