目的 通过分析甲状腺腺瘤和结节性甲状腺肿的声像图及彩色多普勒血流特征 ,探讨甲状腺腺瘤和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 6 9例甲状腺腺瘤与 10 6例结节性甲状腺肿的声像图和彩色多普勒血流显像表现做统计学分析。结果 两组病例中 ,性别、年龄、病灶最大直径、病灶是否液化差异均无显著意义 (P >0 0 5 ) ;双侧叶肿大否、病灶是否单发、病灶有无包膜、病灶周边有否声晕等指标 ,差异均有显著意义 (P <0 0 5 ) ;病灶周边及内部彩色多普勒血流信号的有无、多少差异有显著意义 (P <0 0 5 )。结论 声像图特征和彩色多普勒血流信号特点可诊断甲状腺腺瘤和结节性甲状腺肿
Objective To analyze the echocardiographic features and color Doppler flow characteristics of thyroid adenoma and nodular goiter to discuss the key points in the differential diagnosis of thyroid adenoma and nodular goiter. Methods Sixty-nine cases of thyroid adenoma and 106 cases of nodular goiter confirmed by surgery and pathology were analyzed by sonography and color Doppler flow imaging. Results There was no significant difference in gender, age, maximum diameter of lesions and liquefaction between the two groups (P> 0.05); bilateral lobes were not enlarged, the lesions were single, the lesions were surrounded by the capsule, (P <0.05). There was a significant difference in the presence or absence of color Doppler flow signals between peripheral and internal lesions (P <0.05). Conclusion The features of sonogram and color Doppler flow signal can diagnose thyroid adenoma and nodular goiter
