目的:探讨甲状腺癌彩色多普勒血流特征。方法对我院术后病理检查确诊的137例146个甲状腺癌病灶术前彩色多普勒血流特征进行回顾性总结分析。结果146个甲状腺癌病灶中血流检出率为91.10%,其中周边型血流占26.03%,内部型血流占42.47%,穿入型血流占22.60%;血流分级0级8.90%,Ⅰ级34.93%,Ⅱ级37.67%,Ⅲ级18.49%。甲状腺癌病灶大小与血流分布类型和分级具有相关性,随着病灶直径增大,血流分布类型趋向于穿入型血流,血流分级逐渐增高(r=0.867,P<0.05;r=0.776,P<0.05)。随着甲状腺癌病灶直径增大,最大流速(Vmax)和阻力指数(RI)逐渐增大,不同病灶直径间Vmax和RI两两比较差异均具有统计学意义(P<0.05)。结论彩色多普勒超声检查直径>10 mm 甲状腺癌随着直径增大,血流越来越丰富,血流模式趋向于杂乱,Vmax 和RI 逐渐增大,而直径≤10 mm 甲状腺癌病灶血流不丰富。
目的:探討甲狀腺癌綵色多普勒血流特徵。方法對我院術後病理檢查確診的137例146箇甲狀腺癌病竈術前綵色多普勒血流特徵進行迴顧性總結分析。結果146箇甲狀腺癌病竈中血流檢齣率為91.10%,其中週邊型血流佔26.03%,內部型血流佔42.47%,穿入型血流佔22.60%;血流分級0級8.90%,Ⅰ級34.93%,Ⅱ級37.67%,Ⅲ級18.49%。甲狀腺癌病竈大小與血流分佈類型和分級具有相關性,隨著病竈直徑增大,血流分佈類型趨嚮于穿入型血流,血流分級逐漸增高(r=0.867,P<0.05;r=0.776,P<0.05)。隨著甲狀腺癌病竈直徑增大,最大流速(Vmax)和阻力指數(RI)逐漸增大,不同病竈直徑間Vmax和RI兩兩比較差異均具有統計學意義(P<0.05)。結論綵色多普勒超聲檢查直徑>10 mm 甲狀腺癌隨著直徑增大,血流越來越豐富,血流模式趨嚮于雜亂,Vmax 和RI 逐漸增大,而直徑≤10 mm 甲狀腺癌病竈血流不豐富。

Objective To explore characteristics of color doppler ultrasound in thyroid carcinoma. Methods The study included 137 patients with 146 malignant nodules which were confirmed by pathological diagnosis. The blood flow char-acteristics of color doppler ultrasound were retrospectively analyzed. Results Among the 146 nodules, 91. 10% showed blood flow signals, including peripheral type (26. 03%), internal type (42. 47%) and penetration type (22. 60%). Blood flow classifications showed that 8. 90% of the lesions were grade 0, 34. 93% were grade I, 37. 67% were gradeⅡ, and 18. 94%were grade Ⅲ. The blood flow patterns and grades were relative to the sizes of the nodule. As the sizes increased, the blood flow tended to be penetration type, and blood grade increased (r=0. 867, P<0. 05;r=0. 776, P<0. 05). As the lesion si-zes increased, the Vmax and RI increased, and the differences of Vmax and RI were significant among various sizes of lesions (P<0. 05). Conclusion For those lesions with diameter bigger than 10 mm, blood flow is more abundant along with its size, and blood flow pattern may tend to be clutter, and Vmax and RI increase gradually. While lesions with diameter less than or equal to 10 mm may have low blood flow.
