摘要
目的对比三维时间飞跃法磁共振血管成像(3D TOF-MRA)、增强磁共振血管成像(CEMRA)及数字减影血管造影(DSA)在颅内动脉瘤诊断中的应用效果。方法 86例颅内动脉瘤患者作为研究对象,所有患者均经DSA证实为颅内动脉瘤,后采用3D TOF-MRA、CE-MRA观察所有患者颅内磁共振影像结果 ,对比三种检查方案的诊断结果及应用特点。结果 CE-MRA确诊颅内动脉瘤85例(98.84%),3D TOF-MRA确诊79例(91.86%),两种检查方案确诊结果与DSA诊断结果比较差异无统计学意义(P>0.05)。结论 CE-MRA与3D TOF-MRA在颅内动脉瘤诊断方面具有较高的诊断价值,但对于微小动脉瘤患者3D TOF-MRA诊断能力较弱,存在一定的误诊漏诊现象,应选择CE-MRA进行检查。
Objective To compare application effects of three-dimensional time-of-flight magnetic resonance angiography （3D TOF-MRA）, contrast-enhanced magnetic resonance angiography （CE-MRA） and digital subtraction angiography （DSA） in diagnosis of intracranial aneurysm. Methods A total of 86 intracranial aneurysm patients as study subjects received DSA for verification. Their magnetic resonance images were observed by 3D TOF-MRA and CE-MRA. Diagnostic results and application characteristics of the three methods were compared. Results There were 85 intraeranial aneurysm cases diagnosed by CE-MRA （98.84%） and 79 eases diagnosed by 3D TOF-MRA （91.86%）. Compared with DSA results, there were no statistically significant differences of the two methods（P〉0.05）. Conclusion CE-MRA and 3D TOF-MRA provides highly diagnostic value for intracranial aneurysm, while 3D TOF-MRA is weaker in diagnosis of small aneurysms with misdiagnosis. Thus, CE-MRA is preferred in examination.
