烟雾病(Moyamoya病)诊断的必需条件是,传统血管造影(conventional angiography,CA)显示出颅内动脉有狭窄性变化或出现烟雾血管造影。但是CA具有创伤性,尤其是在儿童并不一定完全安全,不适宜于多次检查,也不适用于随访观察及对高危人群进行筛选。磁共振血管造影(magnetic resonance angiography,MRA)正成为诊断阻塞性脑血管病的另一种可靠方法,无创伤性且在重点医疗机构广泛应用。本研究通过与CA比较,评估MRA诊断烟雾病的准确性。
A prerequisite for the diagnosis of moyamoya disease (Moyamoya disease) is that conventional angiography (CA) shows stenosis of the intracranial artery or smog angiography. However, CA is traumatic, especially in children is not necessarily completely safe, not suitable for multiple examinations, is not suitable for follow-up observation and screening of high-risk groups. Magnetic resonance angiography (MRA) is becoming another reliable method of diagnosing obstructive cerebrovascular disease. It is noninvasive and widely used in key medical institutions. In this study, we evaluated the accuracy of MRA in the diagnosis of moyamoya disease by comparing with CA.
