摘要
目的 探讨能谱CT成像在颈动脉粥样硬化斑块性质评估中的应用及其与脑卒中发生的关系。方法选取2022年1月至2023年1月收治的100例颈动脉粥样硬化斑块或狭窄患者作为研究对象,根据患者是否发生脑卒中将其分为对照组(61例,未发生脑卒中)和观察组(39例,发生脑卒中)。所有患者均接受能谱CT成像检查。比较两组的颈动脉粥样硬化斑块或狭窄检出情况及斑块性质;比较观察组不同性质颈动脉粥样硬化斑块的能谱CT成像特征、能谱参数;采用Spearman相关性分析不同性质颈动脉粥样硬化斑块与脑卒中发生的关系。结果 观察组的颈动脉粥样硬化不稳定斑块、颈动脉狭窄检出率高于对照组(P<0.05)。观察组的纤维斑块、钙化斑块检出率高于对照组,脂肪斑块检出率低于对照组(P<0.05)。观察组不同性质颈动脉粥样硬化斑块的能谱CT成像特征、能谱参数比较,差异具有统计学意义(P<0.05)。纤维斑块、脂肪斑块、混合斑块与脑卒中的发生密切相关(P<0.05)。结论 能谱CT成像能对颈动脉粥样硬化斑块性质进行准确评估,明确颈动脉狭窄情况,还有助于预测脑卒中的发生。
Objective To explore the application of spectral CT imaging in the evaluating the nature of carotid atherosclerotic plaque and its relationship with the occurrence of stroke.Methods A total of 100 patients with carotid atherosclerotic plaque or stenosis admitted from January 2022 to January 2023 were selected as the research objects.The patients were divided into control group(61 cases,no stroke occurred)and observation group(39 cases,stroke occurred)according to whether they had stroke.All patients underwent spectral CT imaging.The detection of carotid atherosclerotic plaques or stenosis and the nature of plaques were compared between the two groups;the spectral CT imaging characteristics and spectral parameters of different nature of carotid atherosclerotic plaques in the observation group were compared;Spearman correlation analysis was used to analyze the relationship between different nature of carotid atherosclerotic plaques and the occurrence of stroke.Results The detection rates of unstable carotid atherosclerotic plaque and carotid artery stenosis in the observation group were higher than those in the control group(P<0.05).The detection rates of fibrous plaque and calcified plaque in the observation group were higher than those in the control group,and the detection rate of fat plaque was lower than that in the control group(P<0.05).There were statistically significant differences in the spectral CT imaging features and spectral parameters of different nature of carotid atherosclerotic plaques in the observation group(P<0.05).Fibrous plaque,fat plaque and mixed plaque were closely related to the occurrence of stroke(P<0.05).Conclusion Spectral CT imaging can accurately evaluate the nature of carotid atherosclerotic plaques,clarify carotid stenosis,and help predict the occurrence of stroke.
