摘要
目的 探讨磁共振动脉血管成像与CT动脉血管成像在脑血管疾病中的诊断价值及各自对比剂特点.方法 选取温州医科大学附属第一医院2015年5月~2016年5月就诊的120例已经确诊的脑血管病患者,先进行磁共振动脉血管成像与CT动脉血管成像检查,其中前者应用顺磁性对比剂,后者应用碘对比剂,并在7天内进行数字减影血管造影检查,并以减影血管造影检查作为诊断标准,对比两种方法对于脑血管疾病的诊断差异.结果 (1)磁共振动脉血管检查、CT动脉血管成像检查在脑动脉狭窄中的特异性为98.20%、90.20%,敏感性为90.90%、100.00%;(2)磁共振动脉血管检查、CT动脉血管成像检查在烟雾病中的特异性分别为95.00%、90.00%,敏感性分别为100.00%、100.00%;(3)磁共振动脉血管检查、CT动脉血管成像检查在脑动脉瘤中的特异性分别为86.44%、85.15%,敏感性分别为100.00%、84.69%.结论 磁共振动脉血管检查在脑动脉瘤诊断中优于CT动脉血管成像检查,所用成像对比剂各有特点,可增强检查效果.
Abstract
Objective To evaluate the diagnostic value of magnetic resonance angiography and CT angiography in cerebrovascular disease and the characteristics of the respective contrast agents. Methods A total of 120 patients diagnosed with cerebrovascular disease in our hospital from May 2015 to May 2016 underwent magnetic resonance angiography and CT angiography, of which the former application of paramagnetic contrast agents, the application of iodine contrast agent, and digital subtraction angiography within 7 d and subtraction angiography as diagnostic standard.Then the results of two methods were compared in diagnosis of cerebral vascular disease. Results The specificity of magnetic resonance arterial examination and CT angiography in cerebral arterial stenosis were 98.20%, 90.20%, the sensitivity were 90.90% and 100%; The specificity of magnetic resonance arterial examination and CT angiography in moyamoya disease were 95.00% and 90.00%, the sensitivity were 100.00% and 100.00%; The specificity of magnetic resonance arterial examination and CT angiography in brain aneurysm were 86.44%, 85.15%, the sensitivity were 100.00%, 84.69%. Conclusion MR angiography is superior to CT angiography in the diagnosis of cerebral aneurysms, and the imaging contrast agents have their own characteristics, which can enhance the effect of the examination.
