摘要
本文报道采用二维及彩色多普勒超声，对５３例经手术病理证实的甲状腺肿块（癌１０例计１２个病灶，腺瘤１６例及结节性甲状腺肿２７例计３９个增生结节）进行探测结果表明，恶性病灶常表现为低回声、边界模糊、边缘不整、内部微小钙化、后方回声衰减及少数肿块周边探及动脉血流，与良性肿块不同，两者之间有显著差异（Ｐ＜０．０５），而在边缘晕、内部血流程度及穿插动脉血管方面，良、恶性肿块之间无显著性差异（Ｐ＞０．０５）。对甲状腺肿块高速血流信号的临床意义及良、恶性肿块的声像图的病理基础亦进行了探讨。
Fifty-three cases with thyroid tumors(10 carcinomas,16 adenomas and 27 nodular goiters)confirmed by operation and pathology were investigated by two-dimensional and color Doppler ultrasonography.The findings were as follows:malignant tumors usually had hypoechoes,indistinct and irregular margins,microcalcification,distal echo attenuation and arterial flow signals at the periphery as compared with benign tumors(P<0.05).But differences in “halo”signs,degree of flow signals and interposed arterial vessels showed no statistical significance(P>0.05).The clinical significance of high-velocity Doppler signals in the tumors and the pathologic basis of various sonographies of benign and malignant tumors are also discussed.
