| 摘要 目的：研究对比头颅电子计算机断层扫描血管造影（CTA）和头颅磁共振血管成像（MRA）在颅内动脉瘤中诊断价值。方法：回顾性分析医院2019年1月2日～2020年12月15日收治的60例疑似颅内动脉瘤患者资料，所有受试者均开展头颅CTA检查、MRA检查以及数字减影血管造影（DSA）检查。以DSA检查结果为金标准，比较头颅CTA和头颅MRA诊断颅内动脉瘤的效能。此外，对比头颅CTA和头颅MRA诊断不同分级、不同部位颅内动脉瘤的符合率。结果：DAS检查结果显示确诊动脉瘤患者48例，共检出动脉瘤74个，CTA检出动脉瘤65个，MRA检出动脉瘤51个，CTA动脉瘤检出率高于MRA检出率（均P＜0.05）。以DSA结果为金标准，CTA诊断颅内动脉瘤的灵敏度、特异度以及准确度分别为94.20%（65/69）、60.00%（3/5）、91.89%（68/74），均高于MRA的82.26%（51/62）、41.67%（5/12）、75.68%（56/74）（均P＜0.05）。CTA诊断1级颅内动脉瘤的符合率为13.85%（9/65），高于MRA的7.84%（4/51）（P＜0.05）。各种检查方式诊断不同部位颅内动脉瘤的符合率对比均无明显差异（均P＞0.05）。结论：CTA诊断颅内动脉瘤的灵敏度、特异度以及准确度均高于MRA，可提高对小直径肿瘤的检出率。然而，MRA具有无辐射、检测费用少、安全性高等优势，临床实际工作中可综合选择合理的检查方式。 |

| ABSTRACT Objective: To study and compare the diagnostic value of cranial computed tomography angiography (CTA) and cranial magnetic resonance angiography (MRA) in intracranial aneurysms. Methods: Data of 60 patients with suspected intracranial aneurysms who were admitted to our hospital from January 2, 2019 to December 15, 2020 were retrospectively analyzed. CTA examination, MRA examination and digital subtraction angiography (DSA) examination were performed on all subjects. Using the results of DSA as the gold standard, the efficacy of cranial CTA and cranial MRA in the diagnosis of intracranial aneurysms were compared. In addition, the coincidence rate of cranial CTA and cranial MRA in different grades and different locations of intracranial aneurysms were compared. Results: DAS examination results showed 48 patients with confirmed aneurysm, a total of 74 aneurysms were detected, 65 aneurysms were detected by CTA, and 51 aneurysms were detected by MRA, and the detection rate of CTA aneurysms was higher than that of MRA (all P＜0.05). Taking DSA results as the gold standard, the sensitivity, specificity and accuracy of CTA in the diagnosis of intracranial aneurysms were 94.20% (65/69), 60.00% (3/5) and 91.89% (68/74), respectively, which were higher than 82.26% (51/62), 41.67% (5/12), 75.68% (56/74) in MRA (all P＜0.05). The coincidence rate of CTA in diagnosis of grade 1 intracranial aneurysm was 13.85% (9/65), which was higher than 7.84% (4/51) of MRA (P＜0.05). There was no significant difference in the coincidence rate of different examination methods in the diagnosis of intracranial aneurysm in different locations (all P＞0.05). Conclusion: The sensitivity, specificity and accuracy of CTA in the diagnosis of intracranial aneurysms are higher than those of MRA, and can improve the detection rate of small diameter tumors. However, MRA has the advantages of no radiation, low test cost and high safety, so a reasonable examination method can be comprehensively selected in clinical practice. |
