目的探讨临床采用常规超声与超声弹性成像诊断甲状腺良恶性结节的临床效果。方法选取获得手术病理证实的51例患者83个甲状腺结节病灶作为研究样本,其中病理诊断为良性病灶56个,恶性病灶27个,并将其与常规超声、超声弹性成像诊断结果进行比较。结果 83个结节病灶的常规超声诊断中良性结节64个,恶性结节19个,主要以结节形态、微钙化、纵横比及阻力指数等为主要鉴别指标;超声弹性成像中良性结节57个,恶性结节26个,主要以弹性成像硬度分级为评估标准。结论在甲状腺良恶性结节的鉴别诊断中超声弹性成像的应用价值显著优于常规超声,对甲状腺结节性质、程度等评估具有良好的指导作用。
Objective To investigate the clinical effect of routine ultrasound and ultrasound elastography in the diagnosis of benign and malignant thyroid nodules. Methods Totally 83 thyroid nodules from 51 patients confirmed by surgery and pathology were selected as the research samples. Among them, 56 were benign lesions and 27 were malignant lesions. The diagnostic results were compared with those by conventional ultrasound and elastography. Results Totally 64 benign nodules and 19 malignant nodules were diagnosed by routine ultrasonography in 83 nodules. The nodules mainly included nodule morphology, micro-calcification, aspect ratio and resistance index. Ultrasound elastography included benign nodules 57, malignant nodules 26, mainly based on the elastic imaging hardness grading as the evaluation criteria. Conclusion The value of ultrasound elastography in the differential diagnosis of benign and malignant thyroid nodules is significantly superior to that of conventional ultrasound in the diagnosis of thyroid nodules. It has a good guiding role in the evaluation of thyroid nodule quality and degree.
