摘要:
目的 探讨超声弹性应变率比值（SR）鉴别甲状腺结节良恶性的价值，分析甲状腺恶性结节的危险因素。方法 选择我院2018年6月~2020年6月经病理确诊的148例甲状腺结节患者（187个结节）作为研究对象，所有受检者行超声检查，以病理诊断为金标准，比较良性结节与恶性结节的SR值以及超声诊断及病理诊断结果，分析超声弹性应变率比值的主要影响因素。结果148例甲状腺结节患者（187个结节）中，甲状腺左叶占45.99%，右叶占54.01%；其中良性结节占62.03%；恶性结节占37.87%。恶性结节SR值较良性结节高，差异有统计学意义（P＜0.05）；SR诊断甲状腺结节良恶性的敏感性为90.14%，特异性为90.52%，准确性为90.43%。单因素分析显示，不同结石深度、形态、内部成分、内部血流及边界等甲状腺结节的SR值比较，差异无统计学意义（P＞0.05）；而不同结节最大径及钙化程度的甲状腺结节的SR值比较，差异有统计学意义（P＜0.05）；二元线性回归分析结果显示，结节的最大径、钙化是影响超声弹性应变率比值的独立影响因素。结论 SR值可作为鉴别甲状腺结节良的指标之一，其敏感性、特异性及准确性均较好；另外，结节的最大径、钙化是影响SR值的独立影响因素，临床诊断中应综合考虑上述因素对结节良恶性判定的影响。
Abstract:
Objective To explore the value of ultrasonic elastic strain rate ratio (SR) in distinguishing benign and malignant thyroid nodules, and to analyze the risk factors of malignant thyroid nodules.Methods 148 patients with thyroid nodules (187 nodules) who were pathologically diagnosed in our hospital from June 2018 to June 2020 were selected as the research objects.All subjects underwent ultrasound examination, with pathological diagnosis as the gold standard, comparing the SR values of benign and malignant nodules, as well as the results of ultrasound diagnosis and pathological diagnosis, and analyzing the main influencing factors of the ratio of ultrasound elastic strain rate.Results Among 148 patients with thyroid nodules (187 nodules), the left lobe of the thyroid accounted for 45.99% and the right lobe accounted for 54.01%; among them, benign nodules accounted for 62.03%;Malignant nodules accounted for 37.87%. The SR value of malignant nodules was higher than that of benign nodules,the difference was statistically significant (P＜0.05);The sensitivity of SR in diagnosing benign and malignant thyroid nodules was 90.14%, the specificity was 90.52%, and the accuracy was 90.43%. Univariate analysis showed that there was no statistical difference in the SR value of thyroid nodules with different stone depth, shape, internal composition, internal blood flow and border (P＞0.05);The SR values of thyroid nodules with different maximum diameters and degrees of calcification showed statistical differences (P＜0.05);The results of binary linear regression analysis showed that the maximum diameter and calcification of nodules were independent factors that affect the ratio of ultrasonic elastic strain rate.Conclusion SR can be used as one of the indicators to identify benign thyroid nodules, and its sensitivity, specificity and accuracy are good;In addition, the maximum diameter and calcification of the nodule are independent influencing factors that affect the ratio of ultrasonic elastic strain rate. The clinical diagnosis should comprehensively consider the influence of the above factors on the judgment of benign and malignant nodules.
