[Abstract] Objective： To analyze the clinical value of CT angigraphy （CTA） and magnetic resonance angiography （MRA）in the diagnosis of intracranial aneurysms.Method： From March 2O21 to March 2024，103 patients with highlysuspected intracranial aneurysms received in Guyuan People's Hospital were selectedas the research objects，allthe research subjectsunderwent CTA and MRA examinations.Result： The diagnostic resultsof CTA inpatients withintracranialaneurysmshowedthatitssensitivityandspecificity were higher thanthoseof MRA， and the diagnostic accuracyof patients was alsosignificantly higher than thatof MRA，with statistical significance 0 P <0.05）. Combined with surgical or DSA reference standards， CTA identified 77 true positive cases （74.76% ） whileMRA detected 67truepositives （65.05% ）.There wasa significant difference in the proportion of true positives between the two groups （ P <0.05）.For lesion site detection in patients with intracranial aneurysms，CTA yielded a diagnostic accuracy rate of 97.09% ，which was significantly higher than 73.79% achieved with traditional MRA， withastatisticallysignificantdifference（ P <0.05）.Furthermore，inCTAdiagnoses，theclarityindelineatingthe spatial relationships of intracranial aneurysms was 69.90% ，significantly higher than the 55.34% obtained with MRA （ P <0.05）.Conclusion： In the clinical application of CTA and MRA in the diagnosis of intracranial aneurysms， CTAdetection has relatively higher sensitivity，accuracyand specificity for aneurysm evaluation，and has higher diagnostic value.
