MRI检查在椎动脉狭窄程度评估中的应用价值

The application value of MRI examination in evaluating the degree of vertebral artery stenosis

目的探讨和论证磁共振成像(MRI)血管成像技术在椎动脉狭窄程度评估中的应用价值,为椎动脉狭窄的诊断提供参考。方法选择上海市嘉定区中医医院2021年5月—2022年3月接诊的150例接纳常规MRI椎动脉检查的患者资料进行研究,观察MRI血管成像技术应用于椎动脉狭窄水平评估的效果。结果150例患者经MRI血管成像表明左椎动脉狭窄58例、右椎动脉狭窄89例,评估总狭窄率为98.00%。结论在临床诊断中采用MRI血管成像技术检查可清楚显示出患者椎动脉内部情况,并为临床医生判断管腔尺寸、顺畅情况等提供辅助参考,更好地对颈内动脉与颅内动脉病变情况作出判断,可以对异常颅内动脉狭窄患者开展早期的鉴别诊断,具有很高的检查准确度,且操作方便,值得作为优选检查方式在临床中普及、运用。

Objective To discuss and demonstrate the application value of magnetic resonance imaging(MRI)angiography in the evaluation of vertebral artery stenosis degree,and to provide reference for the diagnosis of vertebral artery stenosis.Methods The vertebral artery examination data of 150 patients diagnosed with conventional MRI angiography were selected from Shanghai Jiading District Hospital of Traditional Chinese Medicine from May 2021 to March 2022 for study,and the effect of MRI angiography on the level assessment of vertebral artery stenosis was observed.Results All 150 patients showed left vertebral artery stenosis in 58 cases and right vertebral artery stenosis in 89 cases through MRI angiography.The estimated total stenosis rate was 98.00%.Conclusion The application of MRI angiography examination in clinical diagnosis could clearly show the internal condition of the vertebral artery of patients,and provide auxiliary reference for clinicians to judge the influence of the size and smoothness of the upper lumen,so as to better judge the lesions of internal carotid artery and intracranial artery.It could carry out early differential diagnosis for patients with abnormal intracranial artery stenosis,with high test accuracy and convenient operation,and was worthy of being popularized and applied in clinical practice as the preferred detection method.
