超声造影在良恶性甲状腺结节诊断中的声像图分析

Ultrasonographic analysis of contrast-enhanced ultrasound in the diagnosis of benign and malignant thyroid nodules

目的对超声造影技术在良恶性甲状腺结节诊断中的声像图进行研究分析。方法选取2015年1月~2016年2月我院收治的拟行外科手术并获取病理分析的甲状腺结节患者42例,共56个病灶,其中良性病灶与恶性病灶均为28个,将良性病灶设为对照组,恶性病灶设为观察组,对两组病灶进行常规超声与超声造影检查,对两组良恶性结节造影的声像图进行比较与分析。结果两组结节的常规超声诊断特征之间存在明显区别;观察组的28个恶性病灶中,环状增强为7.14%,均匀增强为0,不均匀增强为46.43%,向心性为42.86%,弥漫性为3.57%;对照组患者环状增强为39.29%,均匀增强为14.29%,不均匀与向心性增强均为7.14%,弥漫性为32.14%,两组比较,各项超声声像特征均有明显差异,具有统计学意义(P<0.05)。结论良恶性甲状腺结节的声像特征与其病理学之间存在相关性,良恶性甲状腺结节的声像图都有其各自的特点,通过对肿块形态、内部回声、后方回声、边界与钙化灶及颈部淋巴结的肿大情况进行比较分析,发现超声造影对结节良、恶性的诊断与鉴别具有极其重要的意义与价值,值得在临床上进行广泛推广应用。

Objective To study the contrast-enhanced ultrasound technology in the diagnosis of benign and malignant thyroid nodules.Methods42patients with thyroid nodules,a total of56lesions with pseudo surgery and the pathological analysis of in our hospital from January2015to February2016were selected,including28benign lesions and28malignant lesions.The benign lesions were divided into control group,the malignant lesions were divided into observation group.The lesions in the two groups were using conventional ultrasound and contrastenhanced ultrasound.Benign and malignant nodules contrast ultrasonographic were compared and analyzed.Results There was a marked difference between the conventional ultrasonographic features of the two sets of nodules.In the28malignant lesions of the observation group,the ring enhancement was7.14%,the homogeneous enhancement was0,the inhomogeneous enhancement was46.43%,the centripetal sex was42.86%,and the diffuse sex was3.57%.In the control group,the ring enhancement was39.29%,the homogeneous enhancement was14.29%,the inhomogeneous and centripetal enhancement were7.14%,and the diffuse was32.14%.Compared with the two groups,the ultrasonographic features were significantly different,there was significant statistical significance(P<0.05).Conclusion The sonographic features of benign and malignant thyroid nodules are related to pathology.The sonographic features of benign and malignant thyroid nodules have their respective characteristics.Based on the comparison of mass morphology,internal echo,rear echo,boundary and swelling of lymph node calcification and neck,it is found that Ultrasonography is of great significance and value in the diagnosis and differential diagnosis of benign and malignant nodules.It is worth to be widely applied in clinical.
