甲状腺良恶性病变CT征象的诊断与鉴别

【摘要】目的：探讨甲状腺良、恶性病变的CT征象的诊断与鉴别。方法：选取我院收治的120例甲状腺病变患者，观察CT图像中甲状腺病变的密度、钙化、包膜、边缘、强化方式等表现，对比分析良恶性病变之间的不同点，并分析与病理结果的相符率。结果：本组120 例甲状腺病变患者中，术前CT诊断为良性病变89例、恶性病变31例，该诊断和术后病理结果比较，差异无统计学意义（P>0.05）。甲状腺良恶性病变CT征象对比：两者微小钙化、无包膜、边缘不清及病灶是否单发方面具有统计学差异（P<0.05），而在密度是否均匀、有无壁结节及强化方式方面无统计学意义（P>0.05）。结论：甲状腺病变患者采用CT检查进行术前诊断，可以较准确的区分其良恶性；病灶边缘不规则、境界不清，细小钙化、无包膜是甲状腺恶性病变的特征性表现，包膜完整、结节呈囊性多为良性病变，仔细观察CT征象有助于诊断与鉴别。 【关键词】甲状腺；螺旋CT；良恶性病变；诊断；鉴别

CT diagnosis and differential of benign and malignant thyroid lesions

Abstract] Objective: To investigate the CT diagnosis and differential of benign and malignant thyroid lesions. Methods:Selected 120 cases of thyroid lesions admitted in our hospital, observed the CT images performance of density, calcification, capsule, edge methods to strengthen of thyroid lesions.comparative analysised the differences between benign and malignant lesions. and analysised consistent rates with pathological results. Results: In the group of 120 cases of thyroid disease patients, 89 cases were benign lesions,and 31 cases were malignant lesions through preoperative CT diagnosis, the diagnosis consistent rates with pathology results were not statistically significant (P> 0.05). CT features compared between benign and malignant thyroid lesions : There were statistically significant (P <0.05) in microcalcifications, no capsule, whether the edge was unclear, and whether the single lesions, There were not statistically significant (P> 0.05) in whether density was uniform, mural nodules and ways to strengthen. Conclusions: Thyroid disease patients were preoperative diagnosised through preoperative CT inspection, could distinguished more accurate between benign and malignant; lesion edge was irregular, state was unclear, had small calcified, non-malignant were characteristic features of malignant thyroid lesions, capsule was complete, nodules was cystic, were benign lesions mostly, that observated CT signs careful was help for diagnosis and differential.
