The value of magnetic resonance angiography and CT angiography in the diagnosis of cerebrovascular diseases and the characteristics of contrast agents / 中国生化药物杂志

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.
