甲状腺良恶性病变的螺旋CT鉴别诊断.doc

老师，您好！ 审稿老师的意见非常到位，认真修改，并结合审稿意见，做了相应的补充和调整。 1、上篇有点小问题，就是桥本甲状腺炎不是肿瘤，只是良性病变，本文侧重甲状腺良恶性病变的CT诊断鉴别甲状腺良恶性病变的CT诊断鉴别良恶性CT征象对比），用于对良恶性病变的主要CT征象进行比较，对讨论中用于鉴别的特征性表现进行铺垫。由于样本数增加，并经过统计学分析，得出的结论更加准确客观，总体内容比以前更加详细充实。 4、插图格式已根据学报要求修改。 5、参考文献中增加了近期英文文章。 6、讨论部分把原文中的甲状腺病变的CT 甲状腺良恶性病变CT【摘要】目的探讨甲状腺良、恶性病变的CT鉴别。方法院收治的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率。结果P0.05）。甲状腺恶性病变两者微小钙化、无包膜、边缘不清病灶是否单发方面具有统计学差异P0.05），而在密度是否均匀、有壁结节强化方式方面无统计学意义P0.05）。结论边缘不清，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鉴别。 【关键词】甲状腺；螺旋CT；良恶性病变；诊断；鉴别 CT diagnosis and differentialenign and malignant thyroid lesions ZHOU Ming,ZOU Xing-nong,LI Wei Department of Radiology,Wuxi Peoples Hospital Affiliated to NJMU,Wuxi 214023 [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 parative 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
