目的通过分析甲状腺腺瘤和结节性甲状腺肿的声像图与彩色多普勒血流特征,探讨甲状腺腺瘤与结节性甲状腺肿的超声鉴别要点。方法对经手术病理证实的142例甲状腺腺瘤与72例结节性甲状腺肿的二维声像图和彩色多普勒血流显像表现进行分析。结果两组病例中,性别、年龄、病灶大小、病灶是否液化差异均无统计学意义(P>0.05);双侧叶是否肿大、病灶是否单发、病灶有无包膜、病灶周边是否有声晕差异均有统计学意义(P<0.05);病灶周边及内部彩色多普勒血流信号的有无、多少差异有统计学意义(P<0.05)。结论二维声像图特征及彩色多普勒血流信号特点可用于甲状腺腺瘤和结节性甲状腺肿的鉴别诊断。
Objective To analyze the features of thyroid adenoma and nodular goiter by ultrasonography and color Doppler flow characteristics of thyroid adenoma and nodular goiter. Methods Two hundred and seventy-two cases of thyroid adenoma and 72 cases of nodular goiter confirmed by surgery and pathology were analyzed by two-dimensional sonography and color Doppler flow imaging. Results There was no significant difference in gender, age, size of lesion and liquefaction between the two groups (P> 0.05). Whether the bilateral lobes were swollen, whether the lesion was single or not, whether the lesion was surrounded by the capsule or not (P <0.05). There was significant difference between the peripheral and internal color Doppler flow signals (P <0.05). Conclusion The two-dimensional sonographic features and the characteristics of color Doppler flow signals can be used in the differential diagnosis of thyroid adenoma and nodular goiter.
