颅内动脉瘤患者行MR血管成像与CT血管造影的价值研究

Study on the Value of MR Angiography and CT Angiography in Patients with Intracranial Aneurysms

目的探索颅内动脉瘤患者行MR血管成像与CT血管造影的价值。方法方便选取该院2019年2月-2020年2月收治病95例疑似颅内动脉瘤患者为试验对象,均实施MRA、DSA、CTA诊断,以手术确诊或DSA确诊结果为金标准,对比2种诊断方式准确率。结果 3种诊断方式对比测量的瘤颈宽度、瘤体直径,差异无统计学意义(F=0.732、1.356,P>0.05)。同时MRA准确率为76.83%(63/82),敏感度76.83%,漏诊率23.17%,特异度76.92%,误诊率23.08%;CTA准确率为96.34%(79/82),敏感度96.34%,漏诊率3.66%,特异度92.31%,误诊率7.69%,差异有统计学意义(χ^(2)=10.326、10.326、7.485,P<0.05)。结论 MR血管成像与CT血管造影均具有一定诊断价值,但对于颅内动脉瘤患者,选择CT血管造影诊断,更可提高诊断正确率。

Objective To explore the value of MR angiography and CT angiography in patients with intracranial aneurysms.Methods A total of 95 patients with suspected intracranial aneurysms conveniently selected to the hospital from February2019 to February 2020 were selected as the test subjects. MRA, DSA, and CTA were all diagnosed. The result of surgical diagnosis or DSA diagnosis was used as the gold standard, contrast the accuracy of these two diagnosis methods. Results The difference in the tumor neck width and tumor body diameter measured by the three diagnostic methods was not statistically significant(F=0.732,1.356,P>0.05). At the same time, the accuracy of MRA was 76.83%(63/82), the sensitivity was 76.83%, the missed diagnosis rate was 23.17%, the specificity was 76.92%, and the misdiagnosis rate was 23.08%;the accuracy of CTA was 96.34%(79/82), and the sensitivity was 96.34%. The missed diagnosis rate was 3.66%, the specificity was 92.31%, and the misdiagnosis rate was 7.69%,the difference was statistically significant (χ^(2)=10.326, 10.326,7.485,P<0.05). Conclusion Both MR angiography and CT angiography have certain diagnostic value, but for patients with intracranial aneurysms, choosing CT angiography for diagnosis can improve the diagnostic accuracy.
