声速匹配技术在甲状腺良恶性结节鉴别诊断中的价值

摘要

Objective To probe into the values of acoustic velocity matching technique in the differential diagnosis of benign and malignant thyroid nodules.Methods One hundred cases of patients with thyroid nodules treated and undergoing the ultrasonography examination in our hospital from January,2013 to January,2016 were retrospective analyzed,and 50 cases were confirmed benign thyroid nodules by thyroid biopsy or postoperative pathology (benign group),while 50 cases were malignant nodules of thyroid (malignant group).Then,the velocity of sound in 100 cases of patients with thyroid nodules were statistically analyzed,and the differential factors affecting ultrasound in benign and malignant thyroid nodules were analyzed.Results The sound velocity of benign nodules in benign group was (1 567 ± 14)m/s,while the sonic velocity of malignant nodules in malignant group was (1 603±21) m/s,the difference was statistically significant (P ＜0.05).The influence factors of ultrasound in differential diagnosis of benign and malignant nodules were analyzed and found that the anteroposterior nodule diameter and transverse diameter ratio larger than 1,solid nodules,irregular margin,hypoechogenicity and micro calcification was the independent risk factors for malignant nodules.Conclusion The acoustic velocity can provide an objective basis for identifying benign and malignant thyroid nodules.At the same time,the influencing factors are analyzed,and it is found that the anteroposterior diameter and transverse diameter ratio larger than 1.solid nodules,irregular margin,hypoechogenicity and micro calcification are the malignant risk factors.%目的 探讨声速匹配技术应用于甲状腺良恶性结节中的鉴别诊断的价值.方法 回顾性分析2013年1月至2016年1月在我院就诊并行超声检查的100例甲状腺结节患者,经过甲状腺活检或手术后病理证实50例为甲状腺良性结节(良性组),50例为甲状腺恶性结节(恶性组),对100例患者的甲状腺结节患者的声速值进行统计分析,并对甲状腺良恶性结节中影响超声鉴别因素进行分析.结果 良性组患者的良性结节声速测值为(1567±14)m/s,而恶性组患者的恶性结节声速测值为(1 603±21)m/s,差异有统计学意义(P＜0.05).对超声鉴别良恶性的影响因素进行分析,发现结节的前后径和横径比值≥1、实性结节、边缘不规则、低回声以及存在微小钙化是导致恶性结节发生的独立危险因素.结论 声速技术可以为甲状腺结节患者鉴别良恶性提供客观依据,同时对影响因素进行分析,发现前后径和横径比值≥1、实性结节、边缘不规则、低回声以及存在微小钙化也是恶性高危因素.
