摘　　要：目的:探讨高频超声在诊断甲状腺乳头状癌(papillary thyroid carcinoma,PTC)颈部转移性淋巴结中的临床应用价值。方法:选取日照市中医医院2019年11月—2021年11月期间收治的94例疑似PTC患者为医学研究对象,均接受高频超声诊断检查,以病理诊断为金标准,评估诊断价值。结果:病理诊断94例患者中有84例确诊为PTC,高频超声诊断PTC准确度为95.74%,特异度为90.00%,敏感度为96.43%,其PTC良、恶性诊断符合率与病理诊断结果对比差异无统计学意义(P>0.05)。PTC颈部淋巴结转移患者淋巴门回声、皮质区微小钙化、皮质区回声、血流分布,以及淋巴结短径、长径、短径/长径均与未转移患者有较大差异,对比差异有统计学意义(P<0.05)。而在时间-强度曲线参数对比上,转移者PI高于未转移者,TTP低于未转移者,差异有统计学意义(P<0.05)。结论:高频超声有助于PTC颈部淋巴结转移的早发现、早诊断。Objective To explore the clinical value of high frequency ultrasound in the diagnosis of cervical metastatic lymph nodes in papillary thyroid carcinoma(PTC).Methods Ninety-four patients with suspected PTC in our hospital were selected as medical research objects from November 2019 to November 2021.All patients received high frequency ultrasound diagnostic examinations and evaluated their diagnostic value.Results Under pathological diagnosis,84 of 94 patients were diagnosed as PTC.The accuracy of high frequency ultrasound in the diagnosis of PTC was 95.74%,the specificity was 90.00%,and the sensitivity was 96.43%.There was no significant difference between the coincidence rate of benign and malignant PTC diagnosis and pathological diagnosis(P>0.05).Patients with cervical lymph node metastasis of PTC lymphatic portal echo,cortical microcalcification,cortical echo,blood flow distribution,and lymph node short diameter,long diameter,short diameter/longjing were all significantly different from those without metastasis,and the comparison was statistically significant(P<0.05).In the comparison of time-intensity curve parameters,the PI of metastatic patients was higher than that of non-metastatic patients,and the TTP was lower than that of non-metastatic patients.The comparison was statistically significant(P<0.05).Conclusion High frequency ultrasound is helpful for early detection and early diagnosis of cervical lymph node metastasis in PTC.
