摘要
目的探讨高分辨率磁共振诊断缺血性脑血管病的临床应用价值。方法选取2016年2月-2017年2月我院收治的180例疑似缺血性脑血管病患者为研究对象,均行高分辨率磁共振扫描检查,观察缺血性脑血管病影像学表现,并以数字减影血管造影(DSA)检查结果为金标准,评估高分辨率磁共振诊断缺血性脑血管病的效能。结果缺血性脑血管病不同分类经高分辨率磁共振扫描检查均具有典型影像学表现,高分辨率磁共振诊断缺血性脑血管病的灵敏度、特异度、准确度各为90.16%、79.31%、86.67%;偏心性狭窄的大脑中动脉管壁,经高分辨率磁共振T2WI检查提示靠近管腔的高信号带为纤维帽,缺血性脑血管病经高分辨率磁共振扫描提示左侧大脑中动脉长条形斑块伴强化,缺血性卒中高分辨率磁共振成像矢状位平扫和增强序列图像提示左侧大脑中动脉不稳定斑块伴重度狭窄。结论高分辨率磁共振诊断缺血性脑血管病的临床应用价值较高,其可作为缺血性脑血管病的一种安全有效诊断手段。
Objective To investigate the clinical value of high resolution magnetic resonance imaging(MRI) in the diagnosis of ischemic cerebrovascular diseases. Methods 180 patients with suspected ischemic cerebrovascular diseases who were admitted to the hospital from February 2016 to February 2017 were selected as the subjects. All patients were examined by high-resolution MRI. The imaging findings of ischemic cerebrovascular diseases were observed, and the efficiency of high-resolution MRI in the diagnosis of ischemic cerebrovascular diseases was evaluated with the results of digital subtraction angiography(DSA) as the golden standard. Results The high-resolution MRI findings of different types of ischemic cerebrovascular diseases were typical, and the sensitivity, specificity and accuracy of high resolution MRI in diagnosing ischemic cerebrovascular diseases were 90.16%, 79.31% and 86.67%, respectively.The high-resolution MRI T2 WI examination of cerebral middle artery with eccentric stenosis showed that high-signal zone close to the lumen was the fibrous cap, and high-resolution MRI of ischemic cerebrovascular diseases showed that there was enhancement of strip plaques in left middle cerebral artery. The high-resolution MRI sagittal plain scan and enhanced sequence images of ischemic stroke showed that the left middle cerebral artery unstable plaques with severe stenosis. Conclusion High resolution MRI is of high value in the diagnosis of ischemic cerebrovascular diseases. It can be used as a safe and effective diagnostic method for ischemic cerebrovascular diseases.
