摘要
目的:探讨超声对诊断甲状腺肿瘤的作用。方法:收治甲状腺肿瘤患者150例,采用彩色多普勒超声仪进行诊断。结果:150例甲状腺肿瘤患者中,超声诊断与病理诊断一致135例,诊断符合率90.0%,18例甲状腺癌中,超声诊断9例,正确诊断率75.0%。甲状腺癌患者阻力指数0.65±0.21,舒张末期速度7.4±2.6EDcm/秒,收缩期峰值速度18.5±4.6PScm/秒,甲状腺腺瘤患者阻力指数0.59±0.18,舒张末期速度6.9±2.3EDcm/秒,收缩期峰值速度12.5±3.8PScm/秒,两组患者阻力指数和收缩期峰值速比较差异有统计学意义(P<0.05),舒张末期速度比较差异无统计学意义(P>0.05)。结论:瘤体形状、内部回声、内部收缩期峰值速度(PS)、阻力指数(RI)是区别甲状腺肿瘤和甲状腺癌的重要指标。
Objective：To study the effect of ultrasound in the diagnosis of thyroid tumor. Method：To collect 150 cases of thyroid tu-mor patients,from October 2012 to Septem-ber,using color doppler ultrasound instru-ment in diagnosis.Results：In the 150 cases of thyroid tumor patients,135 cases ultra-sound diagnosis is consistent with the patho-logical diagnosis,diagnosis coincidence rate is 90.0%.In 18 cases of thyroid cancer,ultra-sound diagnosis 9 cases,correct diagnostic rate is 75.0%.Thyroid cancer patients resis-tance index 0.65 ±0.21,end diastolic veloci- ty 7.4± 2.6EDcm/s,peak systolic velocity 18.5 ± 4.6PScm/s.Thyroid adenoma patiens resistance index 0.59 ± 0.18,end diastolic velocity 6.9 ± 2.3EDcm/s,peak systolic ve-locity 12.5 ＋ 3.SPScm/s.Resistance index and peak systolicvelocity in both groups have significant difference（P 〈 0.05）,end di-astolic velocity was no significant differ-ence（P 〉 0.05）.Conclusion：The shape of tu-mors,internal echo,interior peak systolic ve-locity（PS）,Resistance index（RI） are impor- tant indexs to distinguish thyroid tumors and thyroid cancer.
