不同诊断方式在颅内动脉瘤和脑血管畸形临床诊断中的应用价值

目的：分析比较CT血管成像（CTA）、磁共振血管造影（MRA）及数字减影，血管造影（DSA）在颅内动脉瘤和脑血管畸形临床诊断中的应用价值。方法 选取2012－01～2013－12间在我院神经内科住院且需进行脑血管检查的83例患者为研究对象，并进行CTA、MRA、DSA检查，比较不同方法对脑血管疾病的诊出率以及发病部位的诊断情况。结果 三种诊断方式对脑血管疾病检出的敏感性无明显差异（P＞0．05）；三种诊断方式对脑血管疾病检出部位无明显差异（P＞0．05），三种检查方式均可用于不同类型脑血管畸形诊断，诊出率无明显差异（P＞0．05），经比较，MRA对小型畸形检出效果较差，CTA对重型畸形检出效果较差。结论 CTA、MRA及DSA对脑血管疾病诊断效果无明显差异，在临床应用时，应综合考虑检查方式利弊，并注意结合患者实际情况进行选择。

Application Value of Different Diagnosis Methods in Intracranial Aneurysm and Vascular Malformation Clinical Diagnosis

Objective To compare the clinical application value of CTA, MRA and DSA in the diagnosis of intracranial aneurysms and cerebrovascular malformation.Methods Selecting 83 patients from January, 2012 to December, 2013 in department of neurology and cere-brovascular examination as the research objects, statistically analyzing CTA, MRA and DSA examination, and comparing diagnosis situation of the examination results of cerebrovascular and disease parts.Results Three methods for diagnosis of cerebrovascular disease detection sensitivity had no obvious difference （P＆gt;0.05）; Three ways could be used for different types of vascular malformations diagnosis, and diagnosed rate had no obvious difference （P＆gt;0.05）.By comparison, the MRA for small anomaly detection effect was poorer.CTA for heavy anomaly detection effect was poorer.Conclusion CTA, MRA and DSA in cerebrovascular disease diagnosis effect has no obvious difference.In clinical application, the advantages and disadvantages inspection must be taken into account, and they should be chosen in combination with the practical situation of patients.
