【Abstract】 ObjectiveTo explore the application value of magnetic resonance angiography （MRA） technology inpatients with intracranialaneurysms.MethodsAtotalof96suspected intracranialaneurysmpatientswho visited ourhospitalfromJanuary 202 to March2O24 were included in the study.Allpatientsunderwent MRAandrotational contrast-enhanced three-dimensional reconstruction（3DR-DSA）examinations.Using surgical results as the "gold standard"，analyze the results of MRAand 3DR-DSA examinations，compare the condition of the aneurysm under the two examination methods，analyze the diagnostic valueof MRAand 3DR-DSA in intracranial aneurysm，and calculate consistency.IANResultsThere wasnostatistically significant diffrence between MRA and 3DR-DSAin the detectionrate of intracranial aneurysm types （>O.O5）.The longitudinal diameterand neck width ofthe tumordetected by MRA wereboth smaller thanthosedetectedbyDR-DSA examination，with statistical diferences （PO.O5）.There was no statisticallysignificantdiference inthediagnostic specificity，accuracy，sensitivity，positive and negative pred-ictive values of MRA and 3DR-DSA in intracranial aneurysms（ P>0.05 ）.The consistency check showed that the diagnostic consistencybetween MRA and 3DR-DSA was good （Kappa=O.739， 0.756，all P<0.001 ）.Conclusion BothMRA and 3DRDSA have highclinicalapplicationvalueinthediagnosisof intracranial aneurysms，so thebest diagn-ostic methodcanbe selected based on the patients'condition in clinical application， which is worth promoting and applying.

颅内动脉瘤是较为严重的脑血管疾病，是颅内动脉管壁异常膨出所致，是导致非创伤性蛛网膜下腔出血的常见因素，会导致脑血管痉挛、脑梗死、脑出血等严重脑血管疾病[12]。（剩余6237字）
