| ［目的］ 探讨彩色多普勒超声对甲状腺微小癌的诊断价值，误诊分析及如何提高对甲状腺微小癌的早期诊断水平。［方法］ 分析36例经手术和病理证实的甲状腺微小癌的彩色多普勒超声诊断及临床治疗资料。［结果］ 彩色多普勒超声诊断与病理诊断符合率为47.22%（17/36），病变性质待定11例（30.56%），误诊为良性病变8例（22.22%）。超声引导下行细针穿刺抽吸细胞学检查阳性率为95%（19/20）。［结论］ 甲状腺微小癌起病隐匿，术前较难确诊，虽然彩色多普勒超声对甲状腺微小癌诊断有其局限性，但对甲状腺微小癌病灶的声像图进行综合分析，选择恰当的手段可提高甲状腺微小癌的早期诊断率。 |

| Abstract: |
| ［Objective］ To discuss the value of color Doppler flow image (CDFI) in the diagnosis of thyroid micro-carcinoma (TMC) and how to improve the diagnostic of TMC. ［Method］ The CDFI features of 36 TMC patients proved by operation and pathology were analyzed. ［Results］ The diagnostic rate of CDFI according with pathological examination was 47.22% (17/36).Uncertain cases were 11 (30.56%) of them, and 8 of them (22.22%) were misdiagnosed as benign lesions. The positive rate of fine-needle aspiration cytology under the guidance of ultrasound was 95% (19/20). ［Conclusion］ The symptom of TMC is not obvious and the diagnosis is difficult to be made before operation. But the early diagnostic rate can be improved by analyzing the image and choosing the proper methods. |
