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。 This article reports the use of two-dimensional and color Doppler ultrasound in 53 cases of pathologically confirmed thyroid mass (10 cases of cancer in 12 lesions, adenoma in 16 cases and nodular goiter in 27 cases, 39 cases of hyperplastic nodules) The detection results showed that malignant lesions often showed hypoechoic, blurred border, incomplete margin, internal microcalcification, posterior echo attenuation and peripheral exploration of a few lumps and arterial blood flow, which were different from benign masses (P <0.05). However, no significant difference was found between benign and malignant tumors in borderline halo, internal blood flow and arterial blood vessels (P> 0.05). The clinical significance of high-speed blood flow signals in thyroid mass and pathological basis of benign and malignant tumors were also discussed.
