目的 设立分析一些指标 ,来合理使用超声、核素检查 ,提高甲状腺癌术前诊断准确率。方法 回顾性分析 1992～ 1998年收治的 112例甲状腺癌病人资料 ,B超检查 10 8例 ,核素检查 48例 ,两者联合检查了 46例。结果 B超敏感性最高 ,发现结节最小直径在 0 .2～ 0 .3cm。核素和体检相似 ,敏感性稍差 ,46例联合检查的病人中 ,40例术前确诊敏感性为 87% ,特异性为 97%。结论 B超应作为甲状腺结节的第一常规检查 ,B超发现砂粒体或不规则钙化有诊断意义 ,而低回声、不均质、包膜和边界不清、结节内部和周围有血流的发现应与核素扫描、性别及肿块质地等结合考虑
Objective To establish a number of indicators for the rational use of ultrasound and radionuclide examinations to improve the preoperative diagnostic accuracy of thyroid cancer. Methods The data of 112 cases of thyroid cancer admitted from 1992 to 1998 were reviewed retrospectively. 108 cases were examined by B-ultrasound and 48 cases were examined by radionuclide. 46 cases were examined jointly. Results The sensitivity of B-ultrasound was the highest, and the minimum diameter of nodules was found to be between 0.2 and 0.3 cm. The similarity between radionuclide and physical examination was slightly less sensitive. Of the 46 patients who were examined jointly, 40 had a preoperative diagnosis of sensitivity of 87% and a specificity of 97%. Conclusions B ultrasound should be used as the first routine examination of thyroid nodules. B-ultrasound was found to be of diagnostic significance for sarcoplasmic or irregular calcification, hypoechoic, inhomogeneous, unclear envelope and border, and blood flow in and around nodules. Findings should be combined with radionuclide scanning, sex, and mass texture
