【摘要】：目的评估三维时间飞跃法(3D-TOF)MRA在筛选温岭社区人群颅内动脉瘤中的诊断价值。方法 2011年9月至2012年8月温岭社区2 124例颅内动脉瘤可疑患者纳入研究,均接受3D-TOF MRA和3D-DSA检查。分析温岭社区人群颅内动脉瘤流行病学数据,3D-TOF MRA检测颅内动脉瘤的有效性及其与3D-DSA检查金标准的一致性。结果 3D-DSA检查显示温岭社区人群颅内动脉瘤发生率为6.87%(146/2 124),其中男71例(48.63%),女75例(51.37%),平均年龄(41.2±11.6)岁;伴随疾病包括高血压、糖尿病、动脉硬化、脑血管疾病。3D-TOF MRA检查显示149例颅内动脉瘤,其中5例为误诊,2例为漏诊,检查灵敏度为98.63%(144/146),特异度为99.72%(1 773/1 778),准确度为99.67%(2 117/2 124)。两种方法检测颅内动脉瘤纵径及颈宽的差异均无统计学意义(P0.05)。结论 3D-TOF MRA检查颅内动脉瘤具有较高的灵敏度、特异度和准确度,其无创性优势更适用于颅内动脉瘤初筛。
[Abstract]:Objective to evaluate the diagnostic value of 3D TOF MRA in the screening of intracranial aneurysms in Wenling community. Methods from September 2011 to August 2012, 2124 patients with suspected intracranial aneurysms in Wenling community were included in the study. All patients were examined by 3D-TOF MRA and 3D-DSA. The effectiveness of 3D-TOF MRA in detecting intracranial aneurysms and its consistency with the standard of 3D-DSA were analyzed. Results 3D-DSA showed the population in Wenling community. The incidence of intracranial aneurysms was 6.87% / 2124%, of which 71 cases were male (48.63%) and 75 cases were female (51.37%), with an average age of 41.2 卤11.6 years. Accompanied diseases including hypertension, diabetes, arteriosclerosis, cerebrovascular diseases. 3D-TOF MRA revealed 149 cases of intracranial aneurysms, of which 5 cases were misdiagnosed and 2 cases were misdiagnosed. The sensitivity of the two methods was 98.633.The sensitivity was 98.633.The specificity was 773/1 778m, and the accuracy was 99.670.There was no significant difference in the longitudinal diameter and neck width of intracranial aneurysms between the two methods. Conclusion 3D-TOF MRA has high sensitivity, specificity and accuracy in the detection of intracranial aneurysms, and there is no significant difference between the two methods in detecting the longitudinal diameter and neck width of intracranial aneurysms (P 0.05), conclusion 3D-TOF MRA is of high sensitivity, specificity and accuracy in the detection of intracranial aneurysms. Its non-invasive advantage is more suitable for primary screening of intracranial aneurysms.
