目的:研究甲状腺结节CT的特征表现及其与病理类型的相关性。方法:回顾性分析80例甲状腺结节患者术前的CT表现特征与术后病理结果的关系,并行统计学检验。结果:80例共计有结节200个,包括148个良性结节和52个恶性结节。良恶性结节的CT表现在数目、形态(χ2=95.11)、囊变(χ2=66.26)、实性部分强化特点(χ2=77.11)及淋巴结肿大方面差异具有显著统计学意义(P<0.05)。结论:结节CT表现为单发、形态不规则、囊变少及实性部分强化不均可提示恶性诊断;甲状腺周围脂肪间隙是否清晰,邻近组织器官是否受侵,是否有颈部淋巴结转移或远处转移是鉴别良恶性结节的主要特征。
Objective: To study the CT features of thyroid nodules and its correlation with pathological types. Methods: A retrospective analysis of 80 cases of thyroid nodules in patients with preoperative CT features and postoperative pathological findings, and statistical tests. Results: There were 200 nodules in 80 cases, including 148 benign nodules and 52 malignant nodules. The CT findings of benign and malignant nodules were statistically significant (P <0.05) in terms of number, shape (χ2 = 95.11), cystic change (χ2 = 66.26), solid enhancement (χ2 = 77.11) and lymph node enlargement ). Conclusion: The nodules with single, irregular shape, less cystic changes and uneven solidification may indicate malignant diagnosis. Whether the fat space around the thyroid gland is clear, adjacent tissue and organ are invading, whether there is cervical lymph node metastasis or not Distant metastasis is the identification of benign and malignant nodules of the main features.
