3.0T HR-MRI在脑动脉粥样硬化和脑动脉炎鉴别诊断中的作用

The Role of 3.0T HR-MRI in the Differential Diagnosis of Cerebral Atherosclerosis and Cerebral Arteritis

目的探究3.0T高分辨率磁共振成像(3.0T HR-MRI)在脑动脉粥样硬化和脑动脉炎鉴别诊断中的作用效果。方法选择我院2020年1月~2022年12月期间接诊的脑动脉粥样硬化、脑动脉炎急性期患者开展研究,按照纳入标准、排除标准,选取40例脑动脉粥样硬化患者为A组、40例脑动脉炎急性期患者为B组,均进行3.0T HR-MRI检查,对比两组鉴别诊断效果。结果A组管壁偏心性增厚占比、偏心性强化占比较B组高,而环形增厚占比、环形强化占比较B组低(P<0.05);A组大脑中动脉占比、颈内动脉颅内段占比较B组高(P<0.05)。结论3.0T HR-MRI的诊断价值较高,可通过判断管壁的增厚及强化方式、患病部位等,准确鉴别区分脑动脉粥样硬化、脑动脉炎,以指导临床医生制定合理化、针对性的治疗方案。

Objective To explore the effect of 3.0T high-resolution magnetic resonance imaging(3.0T HR-MRI)in the differential diagnosis of cerebral atherosclerosis and cerebral arteritis.Methods The patients with cerebral atherosclerosis and cerebral arteritis in the acute phase who were admitted to our hospital from January 2020 to December 2022 were selected for the study.According to the inclusion criteria and exclusion criteria,40 patients with cerebral atherosclerosis were selected as group A and 40 patients with cerebral arteritis in the acute phase as group B.All patients were examined with 3.0T HR-MRI,and the differential diagnosis effects of the two groups were compared.Results The proportion of eccentric thickening and eccentric strengthening of tube wall in group A was higher than that in group B,while the proportion of annular thickening and annular strengthening was lower than that in group B(P<0.05);The proportion of middle cerebral artery and intracranial segment of internal carotid artery in group A was higher than that in group B(P<0.05).Conclusion The diagnostic value of 3.0T HR-MRI is high.It can accurately differentiate cerebral atherosclerosis and cerebral arteritis by judging the thickening and strengthening mode of the tube wall,and the location of the disease,so as to guide clinicians to formulate a reasonable and targeted treatment plan.
