【摘要】：目的:探讨CT征象在甲状腺结节诊断中的意义。方法:回顾性分析经手术病理确诊的30例甲状腺结节(38个结节)的CT平扫及三期增强扫描图像,由2名及以上高年资医师对所有CT征象进行判读,结合病理资料,分析CT各征象对甲状腺结节良恶性鉴别的价值。结果:33个良性结节表现为边界清晰,有完整或不完整强化包膜,结节实性部分明显强化,有不强化囊变坏死区,强化时间密度曲线27个为流出型,6个良性结节因囊性部分多,实性部分少,无法准确测量CT值,无法分型,4个结节出现钙化,形态为斑状、结节状、环状粗钙化,1例甲状腺多发结节患者颈Ⅵ区出现相同表现形式结节;5个恶性结节表现为边界模糊,无包膜,时间密度曲线为缓升平台型,3例有区域性淋巴结转移,2个结节出现钙化,为斑点状成簇分布钙化。结论:依据有无淋巴结转移判定甲状腺结节良恶性是首要指标;结节边界、有无包膜、钙化形态、时间密度曲线等CT征象是进行甲状腺结节良恶性鉴别的有效方法。
[Abstract]:Objective: to investigate the significance of CT findings in the diagnosis of thyroid nodules. Methods: Ct plain and three phase enhanced CT images of 30 cases of thyroid nodules (38 nodules) confirmed by operation and pathology were retrospectively analyzed. All CT signs were interpreted by two or more senior medical practitioners. Combined with pathological data, the value of CT signs in differentiating benign and malignant thyroid nodules was analyzed. Results: the boundary of 33 benign nodules was clear. There were complete or incomplete enhancement of capsule, solid part of nodular enhancement, dead zone of no enhancement of cyst, 27 time density curves of enhancement were efflux, 6 benign nodules could not accurately measure CT value because of more cystic part and less solid part. It was impossible to type, 4 nodules appeared calcification, the shape of them were speckled, nodular, annular coarse calcification, one case of thyroid multiple nodule had the same appearance in neck 鈪，
