目的：探讨CT对甲状腺病变的诊断价值。材料与方法：分析经手术病理或临床生化证实的48例甲状腺病变的CT表现，其中甲状腺腺瘤20例，腺癌12例，Graves病3例，桥本氏甲状腺炎2例，多结节性甲状腺肿11例。全部病例行CT平扫，45例增强。结果：全部病例均显示低密度灶，最小病灶为6mm,CT术前定性诊断准确率为83．3％。3例胸内甲状腺全部由CT首先检出，钙化以多结节性甲状腺肿多见，占54．6％。12例腺癌中，5例侵犯气管食管沟，引起喉结构破坏；3例血管境界不清或被包绕，6例淋巴结转移。结论：CT是诊断甲状腺病变最有价值的检查方法之一，尤其是明确甲状腺癌浸润周围或邻近组织的情况以及有无淋巴结转移，为确定治疗方案及估计预后提供重要依据，但对于不典型的甲状腺病变术前鉴别良恶性有一定困难。
Objective: To investigate the diagnostic value of CT in thyroid lesions. Materials and Methods: CT findings of 48 cases of thyroid lesions confirmed by pathology or clinical biochemistry were analyzed. Among them, there were 20 cases of thyroid adenoma, 12 cases of adenocarcinoma, 3 cases of Graves disease, 2 cases of Hashimoto’s thyroiditis, Goiter in 11 cases. CT scan of all cases, 45 cases enhanced. Results: All cases showed low-density lesions, the minimum lesion was 6mm, the accuracy of qualitative diagnosis before CT was 83.3%. Three cases of thymus thyroid were all detected by CT, calcification with multiple nodular goiter more common, accounting for 54.6%. Among the 12 cases of adenocarcinoma, 5 cases invaded the tracheoesophageal groove, causing the destruction of the laryngeal structure. Three cases had unclear or encircled vessels and 6 cases had lymph node metastases. Conclusion: CT is one of the most valuable methods for the diagnosis of thyroid lesions. In particular, it can clarify whether thyroid carcinoma infiltrates the surrounding or adjacent tissues and whether there is lymph node metastasis. It provides an important basis for the determination of treatment and prognosis, but for atypical Preoperative identification of benign and malignant thyroid have some difficulties.
