摘　　要：目的通过对甲状腺常见病变(甲状腺腺瘤、甲状腺癌和结节性甲状腺肿)的CT表现及ECT表现的分析,探讨甲状腺病变的影像学诊断特点。方法根据手术病理结果,对42例甲状腺病变的CT及其中1 9例ECT表现进行观察分析。结果甲状腺腺瘤15例,CT主要表现为形态规则,边缘光整的结节,呈岛状强化。ECT多为"凉"或"温"结节。甲状腺癌13例,CT表现为形态不规则,边缘模糊,密度不均匀,可见细沙粒状钙化,呈不均匀强化,ECT多为"冷"结节。结节性甲状腺肿14例,CT表现为多发结节,边缘不清,密度均匀,增强呈中等度强化,ECT为"温"结节。结论CT对甲状腺肿瘤的诊断有一定的价值,结合ECT对核素的摄取能力能更好地提高甲状腺肿瘤的定性诊断定性。Objective Through CT and ECT manifestations of analysing to ordinary thyroid diseases including thyroid adenoma, thyroid carcinoma and nodal goitre,to evalute the imaging characters of thyroid diseases. Methods According to results of the histopathology, CT manifestations of 42 cases containing 19 ECT were obersved and analysed. Results Fifteen cases of thyroid adenoma displayed that focuses had regular shapes, sharped margins, nodal enhancement. ECT showed ＂cool＂ or ＂warm＂ nodes.Thirteen cases of thyroid carcinoma displayed that focuses had irregular shapes, blurry margins, unhomogeneous densities and unhomogeneous enhancement with fine calcify. ECT showed ＂cold＂ nodes.Fourteen cases of nodal goitre displayed that focuses were multi-nodes,blurry margins, homogeneous densities and middle enhancement. ECT showed＂warm＂ nodes. Conclusions CT examination has definite values. Thrugh consulting to nuclide congregatting of ECT,the veracity of diagnosis can be more promoted.
