Through the CTA and DSA examination of 50 patients with intracranial aneurysm, and comparative analysis of the results, it was found that CTA and DSA have high consistency and reliability in the diagnosis of intracranial aneurysms. At the same time, through the discussion of CT angiography technology, it was found that it has the advantages of non-invasive and high imaging quality, but there are certain limitations for the detection of some small blood vessels. In summary, CTA and DSA have certain advantages and limitations in the diagnosis of intracranial aneurysms, and appropriate examination methods should be selected according to specific circumstances.Keywords: CTA, DSA, intracranial aneurysm, CT angiography
