目的探究临床对甲状腺良恶性结节用超声检查方式鉴别诊断的临床应用价值。方法对本院2013年-2016年期间收治经穿刺活检病理/手术确认为甲状腺结节患者328例相关临床数据进行回顾性分析,所有患者均接受超声检查诊断,分析患者一般资料后归纳超声检查后良恶性结节的回声特点、结节内部结构以及图像特征。结果相对于良性结节,恶性结节患者中存在纵/横比例超过1的例数明显更高,组间差异统计学处理提示有意义(P<0.05);彩色多普勒血流显像情况如下:在240例良性结节患者中有98例结节血流Alder评定在2级/3级,在例恶性结节患者中有88例结节血流Alder评定在2级/3级,组间差异统计学处理提示有意义(P<0.05);对患者进行PSV、RI检测,提示恶性结节患者血流内相关指标明显高于良性结节患者,组间差异统计学处理有意义(P<0.05),频谱形态之间存在差异。结论对甲状腺结节性病变患者而言用超声手段进行检查能够取得较好的诊断效果,要求医生对患者综合考虑并结合二维、彩色多普勒超声图像等特点,最大程度提升对甲状腺良性与恶性结节的鉴别准确率。
Objective To investigate the clinical value of differential diagnosis of benign and malignant thyroid nodules by ultrasonography. Methods The clinical data of 328 cases with thyroid nodules confirmed by pathological biopsy / surgery during 2013 to 2016 in our hospital were retrospectively analyzed. All the patients were diagnosed by ultrasound. After analyzing the general data of patients, Echogenic characteristics of benign and malignant nodules, nodule internal structure and image features. Results Compared with benign nodules, there was a significantly higher number of cases with malignant nodules with a ratio of more than 1 in the longitudinal and transverse directions, and statistically significant differences between the groups suggested significant (P <0.05); color Doppler flow imaging As follows: 98 out of 240 patients with benign nodules had an Alder rating of grade 2 / grade 3 in the nodule, Grade II / 3 in 88 nodules with malignant nodules (P <0.05). PSV and RI were detected in patients with malignant nodules, which indicated that the relevant indexes of blood flow in patients with malignant nodules were significantly higher than those in benign nodules <0.05), there are differences between the spectral patterns. Conclusions For patients with thyroid nodules, ultrasonic examination can achieve better diagnostic results, requiring doctors to consider the patients combined with two-dimensional, color Doppler ultrasound images and other characteristics, to maximize the promotion of thyroid benign and Identification of malignant nodules accuracy.
