摘要
目的探析常规高频超声联合超声弹性成像对甲状腺良恶性结节鉴别诊断的效能及诊断符合率。方法选取2021年4月至2022年3月于菏泽市牡丹人民医院经临床诊断为甲状腺结节的100例患者(107个甲状腺结节)作为研究对象,所有患者均采用常规高频超声及超声弹性成像进行检查,比较不同甲状腺结节常规高频超声及超声弹性成像特征,以病理活检结果为金标准,比较常规高频超声、超声弹性成像及联合检查的诊断效能及诊断符合率。结果病理活检结果显示,107个结节中,良性结节70个,恶性结节37个。常规高频超声下,良性甲状腺结节低回声占比低于恶性甲状腺结节,等回声、强回声占比均高于恶性甲状腺结节,微钙化灶占比低于恶性甲状腺结节,边界形状清晰光滑及形态规则占比均高于恶性甲状腺结节,差异有统计学意义(P<0.05)。超声弹性成像检查结果显示,良性甲状腺结节弹性成像0~Ⅱ级占比高于恶性甲状腺结节,Ⅲ~Ⅴ级占比低于恶性甲状腺结节,差异有统计学意义(P<0.05)。联合检查诊断符合率、阳性预测值、阴性预测值、灵敏度、特异度、正确指数均高于常规高频超声及超声弹性成像单独检查,差异有统计学意义(P<0.05),而常规高频超声、超声弹性成像上述诊断效能指标比较差异均无统计学意义。结论在甲状腺良恶性结节鉴别诊断中应用常规高频超声能显示甲状腺不同性质结节的形态征象,利用超声弹性成像技术可根据组织弹性分级判断结节性质,而联合检查可提升甲状腺结节性质鉴别诊断效能。
Objective To investigate the efficacy and diagnostic accuracy of conventional high-frequency ultrasound combined with ultrasound elastography in the differential diagnosis of benign and malignant thyroid nodules.Methods 100 patients(107 thyroid nodules)who were clinically diagnosed with thyroid nodules in Heze Peony People's Hospital from April 2021 to March 2022 were selected as the study subjects,and all the pa-tients were examined by conventional high-frequency ultrasound and ultrasound elastography,and the characteristics of conventional high-frequency ultrasound and ultrasound elastography of different thyroid nodules were compared,and took the results of pathological biopsy as the gold standard,the diagnostic efficacy and diagnostic compliance rate of conventional high-frequency ultrasound,ultrasound elastography and combined examination were compared.Results Pathologic biopsy showed,70 benign and 37 malignant nodules out of 107 nodules.Under conventional high-frequency ultrasound,the percentage of hypoechoic benign thyroid nodules was lower than that of malignant thyroid nodules,the percentage of isoechoic and strong echogenicity were higher than thsoe of malignant thyroid nodules,the percentage of microcalcified foci was lower than that of malignant thyroid nodules,the percentage of clear and smooth border shapes and regular morphology were higher than those of malignant thyroid nodules,and the differences were statistically significant(P<0.05).The results of ultrasound elastography showed that the percentage of benign thyroid nodules with elastography grade 0-Ⅱwere higher than those of malignant thyroid nodules,and the percentage of gradeⅢ-Ⅴwere lower than those of malignant thyroid nodules,and the differences were statistically significant(P<0.05).The diagnostic accuracy rate,positive predictive value,negative pre-dictive value,sensitivity,specificity,and correctness index of the combined test were higher than those of the conventional high-frequency ultrasound and ultrasound elastography alone,an
