彩色多普勒超声对甲状腺肿块鉴别诊断的价值

Value of color doppler ultrasound in the differential diagnosis of thyroid tumor

目的探讨彩色多普勒超声对甲状腺肿块鉴别诊断的价值。方法应用彩色多普勒超声检查甲状腺肿块的结果与术后病理结果进行对比。结果全组87例中,经超声诊断为甲状腺腺瘤30例,结节性甲状腺肿10例,桥本氏病4例,甲状腺癌43例;经术后病理检查为甲状腺腺瘤27例,结节性甲状腺肿8例,桥本氏病3例,甲状腺癌29例。甲状腺良性肿块和甲状腺癌超声诊断与术后病理诊断符合率分别为86.36%(38/44)和67.44%(29/43)(χ2=4.40,0.01<P<0.05),误诊率分别为13.64%(6/44)和32.56%(14/43()χ2=4.40,0.01<P<0.05)。结论彩色多普勒超声对甲状腺良性肿块的诊断符合率高,有重要的诊断价值,对甲状腺癌缺乏有力的诊断依据。

Objective To probe the value of color doppler ultrasound in the differential diagnosis of thyroid tumor. Methods The results preoperative ultrasonography for thyroid tumor were compared with postoperative pathology. Results In the 87 cases, the coincident rate of ultrasound with pathology was 86.36% （38/44） and 67.44% （29/43） （X^2 =4.40, 0.0 1〈P〈0.05 ） for thyroid benign tumor and thyroid cancer, while 13.64% （6/44） and 32.56% （14/43） （X^2 =4.40, 0.01〈P〈0.05） for the inaccurate rate of ultrasound with pathology. Conclusion The color doppler ultrasound shows important value in the diagnosis of thyroid benign tumor while provides little diagnostic value for thyroid cancer.
