彩色多普勒对隐匿性甲状腺癌的诊断价值

目的探讨彩色多普勒对隐匿性甲状腺癌的诊断价值。方法对80例经手术及病理诊断为隐匿性甲状腺癌患者的超声检查结果进行回顾性分析。结果本组80例患者中，单发癌结节45例（56．3％），多发癌结节35例（43．8％）；135个病灶声像图中，边界不清的64个（47．7％），边界清无包膜的有66个（48．9％），边界清有晕环的5个（3．7％）；结节内呈低或稍低回声型的100个（74．1％），混合性的28个（20．7％），稍强回声的7个（5．2％）；结节内有血流信号50个（37．O％），其中较丰富者35个（70．0％），呈条状血流信号者15个（30．0％）；35例甲癌中，结节中出现微钙化的31（88．6％），粗钙化3例（9．7％），弧形钙化1例（2．9％）。结论彩色多普勒检查对隐匿性甲状腺癌具有重要的诊断价值。

The diagnostic value of Doppler sonography in patients with occult carcinoma thyroid (OCT)

Objective To evaluate the diagnostic value of Doppler sonography in occult carcinoma of the thyroid(OCT) and its ultrasound features.Methods Uhrasonography and clinical data of 80 cases with OCT confinned by operative pathology were analyzed retrospectively.Results In 80 cases with OCT,a single cancer nodules in 45 cases(56.3%),more than 35 cases of cancer nodules(43.8%);In 135 focus imaging,among border not clear 64 focus(47.7%),the border clear no envelope of 66 focus (48.9%),the border clearance of a halo 5 focus (3.7%);The nodules were slightly lower echo of 100 focus(74.1%),mixed 28 focus(20.7%),slightly stronger echo of 7 focus(5.2%);35 cases of a cancer;the 50 focus showed nodules with blood flow,in which rich 35 focus (70.0%),strip-signal blood flow 14 focus(30.0%);In 35 cases with OCT,among nodular micro-calcification appeared in the 31 cases(88.6%),coarse calcification in 3 cases(9.7%),1 case of arc-shaped calcification(2.9%).Conclusion The diagnosis value of high-frequency sonography was significance in patients with OCT.
