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。Objective To explore the diagnostic efficacy and imaging signs of multi-slice spiral CT in thyroid nodular lesions.Methods 120 patients with thyroid nodular lesions were examined by multi-slice spiral CT.The results of pathological examination were taken as the gold standard,and the efficacy and consistency with the pathological examination results of multi-slice spiral CT in the diagnosis of thyroid nodular lesions were analyzed.The CT signs of benign and malignant thyroid lesions were compared.Results The sensitivity,specificity and accuracy of multi-slice spiral CT in the diagnosis of thyroid nodular lesions were 85.9%,69.0%and 80.0%,respectively.Kappa analysis showed that the consistency between multi-slice spiral CT in the diagnosis of thyroid nodular lesions and pathological examination results was good(Kappa value=0.556,P<0.001).The proportions of edge blurring,uneven density,irregular shape and incomplete capsule of malignant thyroid lesions were significantly higher than those of benign lesions(P<0.05).Conclusions Multi-slice spiral CT has high diagnostic efficiency for thyroid nodular lesions,which can be used for differential diagnosis by analyzing CT signs such as lesion edge,density,shape and capsule.
