摘要
目的:探讨结节纵横比及强化残圈征在CT增强扫描鉴别甲状腺良恶性结节中的价值。方法:回顾性分析104例患者(共143枚甲状腺结节)的CT增强扫描图像,测量结节的纵横比,并观察有无强化残圈征,比较纵横比单独应用及其联合强化残圈征对甲状腺良恶性结节的鉴别诊断效能。结果:甲状腺良恶性结节的纵横比及有无强化残圈征比较,差异均有统计学意义(均P<0.001)。恶性结节的纵横比大于良性结节,以纵横比>1.08鉴别恶性结节,AUC为0.806,敏感度为82.8%,特异度为72.2%。恶性组64枚结节中23枚(35.9%)出现强化残圈征,而良性组79枚结节中仅9枚(11.4%)。纵横比与强化残圈征联合应用的AUC及敏感度较单独应用纵横比升高。结论:运用CT增强扫描测量结节纵横比,并观察有无强化残圈征,对甲状腺良恶性结节有较高的鉴别诊断价值,2项指标联合可进一步提高鉴别诊断效能。
Objective:To evaluate the value of the anteroposterior to transverse diameter ratio and enhanced residual circle sign on enhanced CT for differentiating benign and malignant thyroid nodules.Methods:Imaging data of 104 patients with 143 thyroid nodules confirmed pathologically were analyzed retrospectively.The anteroposterior to transverse diameter ratio of nodules was measured,and the enhancement of the residual circle sign was observed.The differential diagnostic efficiency by application of the anteroposterior to transverse diameter ratio alone and it combined with enhanced residual circle sign to thyroid nodules was compared.Results:The anteroposterior to transverse diameter ratio and enhanced residual circle sign were significantly different in benign and malignant thyroid nodules(P<0.001).The anteroposterior to transverse diameter ratio of malignant nodules was larger than that of benign nodules,and malignant nodules were differentiated by an anteroposterior to transverse diameter ratio>1.08,with AUC of 0.806,sensitivity of 82.8%and specificity of 72.2%.Twenty-three(35.9%)of 64 malignant nodules showed an enhanced residual circle sign,while only 9(11.4%)of 79 benign nodules showed an enhanced residual circle sign.AUC and sensitivity by application of the two indexes combined were higher than those of the anteroposterior to transverse diameter ratio alone.Conclusions:CT-enhanced scanning to measure the anteroposterior to transverse diameter ratio and observe whether there is an enhanced residual circle sign has a higher value in differentiating benign and malignant thyroid nodules,and combining the two indexes can further improve the differential diagnosis efficiency.
