2023年2月第30卷第2期多层螺旋CT对甲状腺结节性病变的诊断效能及影像学征象分析李鹤，杨新焕（郑州人民医院医学影像科，河南郑州450053）【摘要】目的探讨多层螺旋CT对甲状腺结节性病变的诊断效能及影像学征象。方法120例甲状腺结节性病变患者均进行多层螺旋CT检查，以病理检查结果为金标准，分析多层螺旋CT诊断甲状腺结节性病变的效能以及与病理检查结果的一致性，比较甲状腺良、恶性病变的CT征象。结果多层螺旋CT诊断甲状腺结节性病变的敏感度为85.9%，特异度为69.0%，准确度为80.0%。Kappa分析显示，多层螺旋CT诊断甲状腺结节性病变与病理检查结果的一致性良好（Kappa值=0.556，P＜0.001）。甲状腺恶性病变的边缘模糊、密度不均匀、形状不规则、包膜不完整占比均显著高于良性病变（P＜0.05）。结论多层螺旋CT对甲状腺结节性病变的诊断效能较高，可通过分析病灶边缘、密度、形状、包膜等CT征象进行鉴别诊断。【关键词】多层螺旋CT；甲状腺结节性病变；诊断效能；CT征象中图分类号：R445.3文献标识码：Adoi:10.3969/j.issn.1674-4659.2023.02.0167AnalysisofDiagnosticEfficacyandImagingSignsofMulti-SliceSpiralCTinThyroidNodularLesionsLIHe,YANGXinhuan(DepartmentofMedicalImaging,ZhengzhouPeople'sHospital,Zhengzhou450053,China)[Abstract]ObjectiveToexplorethediagnosticefficacyandimagingsignsofmulti-slicespiralCTinthyroidnodularlesions.Methods120patientswiththyroidnodularlesionswereexaminedbymulti-slicespiralCT.Theresultsofpathologicalexaminationweretakenasthegoldstandard,andtheefficacyandconsistencywiththepathologicalexaminationresultsofmulti-slicespiralCTinthediagnosisofthyroidnodularlesionswereanalyzed.TheCTsignsofbenignandmalignantthyroidlesionswerecompared.ResultsThesensitivity,specificityandaccuracyofmulti-slicespiralCTinthediagnosisofthyroidnodularlesionswere85.9%,69.0%and80.0%,respectively.Kappaanalysisshowedthattheconsistencybetweenmulti-slicespiralCTinthediagnosisofthyroidnodularlesionsandpathologicalexaminationresultswasgood(Kappavalue=0.556,P<0.001).Theproportionsofedgeblurring,unevendensity,irregularshapeandincompletecapsuleofmalignantthyroidlesionsweresignificantlyhigherthanthoseofbenignlesions(P<0.05).ConclusionsMulti-slicespiralCTha...
