摘要
目的比较超声弹性成像、二维超声及能谱CT对甲状腺良、恶性结节诊断价值。方法以2018年1月至2019年6月于本院检查并经术后病理证实的75例(104个结节)甲状腺结节患者为研究对象,患者均有完整二维超声、超声弹性成像及能谱CT影像报告,以病理诊断结果为“金标准”,分析超声弹性成像、二维超声及能谱CT对甲状腺良、恶性结节诊断效能。结果75例患者104个结节,经病理证实良性结节73个,恶性结节31个;超声检查根据TIRADS分类,检出良性78个,恶性26个;弹性成像根据色彩评分检出良性75个,恶性29个;能谱CT根据形态学以及碘浓度、能量曲线斜率阈值进行诊断,检出良性72个,恶性32个。超声诊断甲状腺良、恶性结节灵敏度、特异度、准确度分别为69.23%、83.33%、79.81%;超声弹性成像分别为89.66%、93.33%、92.31%;能谱CT分别为90.61%、97.22%、95.19%。经配对χ^(2)检验两两比较发现,超声弹性成像、能谱CT诊断灵敏度、准确度均显著高于超声(P<0.05),但超声弹性成像、能谱CT比较差异无统计学意义(P>0.05)。结论超声弹性成像、二维超声及能谱CT均可用于甲状腺良、恶性结节诊断,但相比之下超声弹性成像、能谱CT较常规二维超声能更好检出甲状腺结节良恶性状态。
Objective To compare the diagnostic value of ultrasound elastography,two-dimensional ultrasound,and energy spectrum CT on benign and malignant thyroid nodules.Methods 75 patients(104 nodules)with thyroid nodules examined in the hospital and confirmed by postoperative pathology from January 2018 to June 2019 were enrolled in the study.All patients had complete imaging reports of two-dimensional ultrasound,ultrasound elastography,and energy spectrum CT.The pathological diagnostic results were taken as the gold standards to evaluate the diagnostic efficacy of ultrasound elastography,two-dimensional ultrasound,and energy spectrum CT on benign and malignant thyroid nodules.Results There were 104 nodules among 75 patients,and 73 benign nodules and 31 malignant nodules were confirmed by pathology.78 benign and malignant nodules were detected according to the TIRADS classification of ultrasound examination,and 75 benign and 29 malignant nodules were detected according to the color score of elastography.72 benign nodules and 32 malignant nodules were detected according to morphology,iodine concentration,and energy curve slope threshold of energy spectrum CT.The sensitivity,specificity,and accuracy in diagnosing benign and malignant thyroid nodules were 69.23%,83.33%,and 79.81%by ultrasound diagnosis,and were 89.66%,93.33%,and 92.31%respectively by ultrasound elastography,and were 90.61%,97.22%,and 95.19%respectively by energy spectrum CT.The pairwise comparison in paired chi-square test showed that the sensitivity and accuracy of ultrasound elastography and energy spectrum CT were significantly higher than those of ultrasound(P<0.05),but there were no significant differences between ultrasound elastography and energy spectrum CT(P>0.05).Conclusion Ultrasound elastography,two-dimensional ultrasound,and energy spectrum CT can be used to diagnose benign and malignant thyroid nodules.However,ultrasound elastography and energy spectrum CT can better detect benign and malignant thyroid nodules than conventional two-dimensional ultrasound.
