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