摘　　要：目的旨在研究良、恶性甲状腺结节CT征象鉴别及其临床应用价值。方法回顾分析本院2017年5月至2019年7月收治76例甲状腺结节患者的临床资料,所有患者均进行MSCT检查。对患者所得图像进行分析,比较良、恶性结节的CT征象差异,以及其结节各期CT值、结节大小直径差异。结果两者在有无包膜、有无淋巴结转移、边界清晰与否等比较中差异有统计学意义,良性结节主要表现为有包膜、无淋巴结转移且结节边界清晰;恶性结节多无包膜,边界不清晰(P<0.001);良、恶性甲状腺结节直径大小、平扫期、延迟期、动脉期CT值比较无差异(P>0.05)。CT扫描可显示出良、恶性甲状腺结节相关差异。结论CT扫描可为甲状腺结节性质鉴别提供较为全面的参考价值,临床使用价值高,结节边界不清楚、无包膜、有远处转移则高度怀疑为恶性结节;有完整包膜、结节与周围组织分界清晰提示为良性结节。Objective To study the differential diagnosis of CT signs for benign and malignant thyroid nodules and their clinical application value.Methods The clinical data of 76 patients with thyroid nodules admitted to our hospital from May 2017 to July 2019 were retrospectively analyzed.All patients underwent MSCT examination.The images obtained by the patients were analyzed to compare the differences in CT signs between benign and malignant nodules,as well as the differences in CT values and size and diameter of nodules.Results The differences between them were statistically significant in the presence of capsules,lymph node metastasis,and clear borders.Benign nodules mainly showed capsules,no lymph node metastasis,and clear boundaries of the nodule.Malignant nodules showed non-capsules primarily,and the border was not clear(P<0.001).There were no differences in diameter and CT values of the plain scan,delayed phase,and arterial phase between benign and malignant thyroid nodules(P>0.05).CT scans can show differences between benign and malignant thyroid nodules.Conclusion CT scan can provide a more comprehensive reference for the identification of thyroid nodules.It has high clinical value.Nodules with unclear boundaries,no capsules,and distant metastases are highly suspected as malignant nodules.Nodules with complete capsules and clear boundaries with surrounding tissue indicate benign nodules.
