摘要
目的分析能谱CT成像对颈动脉粥样硬化斑块性质评估价值及与脑卒中发生率的关系。方法选取医院2018年1月至2019年10月收治的颈动脉粥样硬化斑块或狭窄患者100例,其中33例患者发生脑卒中将其纳入研究组,另67例患者未发生脑卒中将其纳入对照组。两组患者均接受能谱CT成像检查。结果研究组患者动脉粥样硬化斑块检出率、颈动脉狭窄率高于对照组(P<0.05)。对照组患者共检出132枚斑块,研究组共检出71枚斑块。研究组患者钙化斑块、纤维斑块检出率高于对照组(P<0.05),脂肪斑块检出率低于对照组(P<0.05),混合斑块检出率高于对照组(P>0.05),差异比较无统计学意义。钙化斑块、纤维斑块、脂肪斑块、混合斑块特征管壁增厚率、溃疡率、颅内血管病变率差异比较有统计学意义(P<0.05)。钙化斑块、纤维斑块、脂肪斑块、混合斑块的曲线斜率、有效原子序数差异比较有统计学意义(P<0.05)。结论能谱CT成像能准确评估颈动脉粥样硬化斑块性质,明确颈动脉狭窄程度同时,还能预测脑卒中发生,建议推广使用。
Objective To investigate the evaluation value of atherosclerotic plaque properties by energy CT coronary angiography imaging and its relationship with the incidence of stroke.Methods 100 patients with carotid atherosclerotic plaque or stenosis in our hospital from Jan 2018 to Oct 2019 were enrolled,and divided into two groups according to the presence or absence of stroke,study group(n=67)and control group(n=33).both groups received the energy spectrum CTA imaging.Results The detection rate of atherosclerotic plaque and carotid stenosis in the study group were higher than those in the control group(P<0.05).A total of 132 plaques were detected in the control group and 71 plaques in the study group.Study group had higher detection rates of calcified plaque(P<0.05),fibrous plaque(P<0.05)and mixed plaque(P>0.05)as well as lower detection rate of fatty plaque than those of control group.The detection rate of CTA characteristics including tube wall thickening,ulcer,and intracranial vascular lesion had significant difference in calcified plaques,fibrous plaques,fatty plaques,and mixed plaques(P<0.05).The difference in curve slope and effective atomic number between calcified plaque,fibrous plaque,fatty plaque and mixed plaque was statistically significant(P<0.05).Conclusion Energy CT coronary angiography imaging can accurately evaluate the properties of carotid atherosclerotic plaque,determine the degree of carotid stenosis,and predict the occurrence of stroke.
