【摘要】 目的:分析超声弹性成像与常规超声检查在甲状腺结节诊断中的应用价值。方法:选取130例甲状腺结节患者作为观察对象,所有患者均予以超声弹性成像与常规超声检查,以病理结果为金标准,比较两种检查方法对甲状腺结节良恶性的诊断价值。结果:130例患者的病理诊断结果显示,共有结节143个,其中良性结节118个,恶性结节25个。超声弹性成像的特异度为96.61%(114/118)、灵敏度为88.00%(22/25)、诊断符合率为95.10%(136/143)、阳性预测值为84.62%(22/26)、阴性预测值为97.44%(114/117),明显高于对照组的64.41%(76/118)、44.00%(11/25)、60.84%(87/143)、20.75%(11/53)、84.44%(76/90),差异均有统计学意义(P<0.05)。结论:超声弹性成像技术应用于甲状腺结节患者中能明显提高临床诊断准确度,且能更准确地判断甲状腺结节良恶性,减少假阳性、假阴性病例。更多还原

【Abstract】 Objective: To analyze values of ultrasound elastography and routine ultrasonography in diagnosis of thyroid nodules. Methods:130 cases of thyroid nodules were selected as the observation subjects, and all of them were diagnosed by ultrasound elastography and routine ultrasonography. The pathological results were used as the gold standard. The diagnostic values of the two methods for the diagnosis of benign and malignant thyroid nodules were compared. Results: The pathological diagnosis of the 130 patients showed a total of 143 nodules, including 118 benign nodules and 25 malignant nodules. The specificity, sensitivity, diagnostic coincidence rate, positive predictive value and negative predictive value of ultrasound elastography were 96.61%(114/118), 88.00%(22/25), 95.10%(136/143), 84.62%(22/26) and 97.44%(114/117), separately, which were significantly higher than 64.41%(76/118), 44.00%(11/25), 60.84%(87/143), 20.75%(11/53) and 84.44%(76/90) of the control group, and the differences were statistically significant(P<0.05). Conclusions: Ultrasound elastography can significantly improve the accuracy of clinical diagnosis of the patients with thyroid nodules, and can more accurately determine the benign and malignant thyroid nodules and reduce false positive and false negative cases.更多还原
