超声对单发性结节性甲状腺与甲状腺瘤的鉴别诊断价值

目的：探讨超声对单发性结节性甲状腺肿与甲状腺瘤的鉴别诊断价值。方法：分析比较34例单发结节性甲状腺肿与30例甲状腺腺瘤的二维及彩色多普勒超声声像图。结果：34例单发结节结节性甲状腺与30例腺瘤比较,甲状腺大小、结节大小、结节内回声及周围回声均无显著性差异（P＞0．05）;结节边缘晕环及结节内部和周边血流信号具有显著性差异（P＜0．05）。结论：单发结节结节性甲状腺肿较易误诊为腺瘤,结节边缘晕环及结节内部和周边血流信号可以为鉴别诊断提供一定的帮助。

Differential Diagnostic Value of Ultrasonography Between Solitary Nodular Goiter and Thyroid Adenoma

Objective:To discuss the differential diagnostic value of ultrasonography between solitary nodular goiter and thyroid adenoma.Methods:The 2 DE and CDFI ultrasound images of 34 cases with solitary nodular goiter and 30 cases with thyroid adenoma were analysed and compared.Results:There were no significant differences in the sizes of thyroid glands and nodules,nor were the intranodular and perinodular echoes between the group of nodular goiter and adenoma( P >0 05).There were significant differences in the "halo" sign and intranodular and perinodular blood flow ( P <0 05)between the two groups.Conclusions:Solitary nodular goiters are often easily misdiagnosed as adenoma.The "halo" sign and intranodular and perinodular blood flow may be helpful for differential diagnosis.
