摘要
目的探讨CT血管造影(CTA)与MRI血管造影(MRA)在颅内动脉瘤诊断中的价值。方法选取2019年5月至2021年5月菏泽市定陶区人民医院接诊的100例疑似颅内动脉瘤患者作为研究对象,均行CTA、MRA,比较两种诊断方法的符合率、不同直径病灶检出情况、瘤体直径、瘤颈宽度。结果100例患者经手术/DSA均确诊为颅内动脉瘤,CTA检出97例,诊断符合率97.00%,MRA检出94例,诊断符合率94.00%,两种检测方式诊断符合率比较差异无统计学意义。DSA显示病灶直径<3mm者20例、3~6mm者56例、6~9mm者18例、>9mm者6例。CTA直径<3mm的病灶检出率高于MRA,差异有统计学意义(P<0.05),两种检测方式其他直径病灶检出率比较差异无统计学意义。两种检测方法瘤体直径、瘤颈宽度比较差异无统计学意义。结论CTA、MRA诊断颅内动脉瘤符合率均较高,MRA有无辐射、安全性高等优势,CTA能有效检出直径<3mm的颅内动脉瘤,临床可根据患者实际情况选择检查方法。
Objective To evaluate the value of CT angiography(CTA)and MRI angiography(MRA)in the diagnosis of intracranial aneurysms.Methods 100 patients with suspected intracranial aneurysm treated in Dingtao District People's Hospital of Heze City from May 2019 to May 2021 were selected as the study subjects,and CTA and MRA were performed.The coincidence rate of the two diagnostic methods,the detection of lesions with different diameters,tumor diameter and tumor neck width were compared.Results All 100 patients were diagnosed with intracranial aneurysm by operation/DSA,CTA detected 97 cases,the diagnostic coincidence rate of 97.00%,MRA detected 94 cases,the diagnostic coincidence rate of 94.00%,there was no statistically significant difference in the diagnosis coincidence rate between the two methods.DSA showed that lesion diameter<3 mm in 20 cases,3-6 mm in 56 cases,6-9 mm in 18 cases,and>9 mm in 6 cases.The detection rate of lesions with CTA diameter<3 mm was higher than that of MRA,and the difference was statistically significant(P<0.05).There was no statistically significant difference in the detection rate of lesions with other diameters between the two detection methods.There was no significant difference in tumor diameter and neck width between the two methods.Conclusion Both CTA and MRA have high coincidence rate in the diagnosis of intracranial aneurysm.MRA has the advantages of radiation and high safety.CTA can effectively detect intracranial aneurysm with diameter<3 mm,and the examination method can be selected according to the actual situation of patients.
