目的分析CT及超声检查对甲状腺腺瘤的特征性表现,探讨综合运用影像检查提高甲状腺腺瘤定性准确率。方法收集经手术、病理证实的27例甲状腺腺瘤病例,对其CT及超声检查表现进行比较分析。结果27例甲状腺腺瘤中,CT诊断准确率为746%,表现为腺瘤包膜完整,边界清晰,增强后病灶周边见完整强化环。超声诊断准确率为746%,表现为腺瘤包膜清晰、光滑,瘤体与周围正常甲状腺之间见“晕环征”,其内有血流信号显示。结论CT及超声检查诊断甲状腺腺瘤均有一定优势和局限性,综合运用,优势互补可提高甲状腺腺瘤的诊断准确率。
Objective To analyze the characteristics of thyroid adenoma by CT and ultrasonography, and to explore the methods to improve the qualitative accuracy of thyroid adenoma with image examination. Methods Twenty-seven cases of thyroid adenoma proved by operation and pathology were collected and compared with CT and ultrasonography. Results In 27 cases of thyroid adenoma, the diagnostic accuracy rate of CT was 746%. The result showed complete envelopment of adenoma, clear boundary and complete enhanced ring around the lesion. The diagnostic accuracy rate of ultrasound was 746%, which showed that the adenoma capsule was clear and smooth, and the halo sign was found between the tumor and the surrounding normal thyroid gland. Conclusion CT and ultrasound diagnosis of thyroid adenoma have some advantages and limitations, comprehensive utilization, complementary advantages can improve the diagnostic accuracy of thyroid adenoma.
