目的:分析CT对结节性甲状腺肿与甲状腺癌鉴别诊断的价值。方法:分析经手术病理诊断明确的22例结节性甲状腺肿与19例甲状腺癌的CT表现,统计甲状腺病灶的边缘、密度等征象。结果:结节性甲状腺肿病灶局限,表现为囊性低密度影,边缘光滑,可见到囊壁。恶性甲状腺肿瘤呈等密度或混杂密度,边界不清,强度不均,并向邻近组织侵犯。结论:CT在甲状腺肿瘤的诊断和鉴别诊断中具有重要价值。
Objective: To analyze the value of CT in the differential diagnosis of nodular goiter and thyroid cancer. Methods: The CT manifestations of 22 cases of nodular goiter and 19 cases of thyroid carcinoma were analyzed by pathology. The margins and density of thyroid lesions were analyzed. Results: Nodular goiter lesions were limited, showing cystic low density, smooth edges, visible wall. Malignant thyroid tumors were iso-density or mixed density, the boundary is unclear, uneven intensity, and violations of neighboring tissues. Conclusion: CT is of great value in the diagnosis and differential diagnosis of thyroid tumors.
