【摘要】：目的:探討CT征象在甲狀腺結節(jié)診斷中的意義。方法:回顧性分析經手術病理確診的30例甲狀腺結節(jié)(38個結節(jié))的CT平掃及三期增強掃描圖像,由2名及以上高年資醫(yī)師對所有CT征象進行判讀,結合病理資料,分析CT各征象對甲狀腺結節(jié)良惡性鑒別的價值。結果:33個良性結節(jié)表現(xiàn)為邊界清晰,有完整或不完整強化包膜,結節(jié)實性部分明顯強化,有不強化囊變壞死區(qū),強化時間密度曲線27個為流出型,6個良性結節(jié)因囊性部分多,實性部分少,無法準確測量CT值,無法分型,4個結節(jié)出現(xiàn)鈣化,形態(tài)為斑狀、結節(jié)狀、環(huán)狀粗鈣化,1例甲狀腺多發(fā)結節(jié)患者頸Ⅵ區(qū)出現(xiàn)相同表現(xiàn)形式結節(jié);5個惡性結節(jié)表現(xiàn)為邊界模糊,無包膜,時間密度曲線為緩升平臺型,3例有區(qū)域性淋巴結轉移,2個結節(jié)出現(xiàn)鈣化,為斑點狀成簇分布鈣化。結論:依據(jù)有無淋巴結轉移判定甲狀腺結節(jié)良惡性是首要指標;結節(jié)邊界、有無包膜、鈣化形態(tài)、時間密度曲線等CT征象是進行甲狀腺結節(jié)良惡性鑒別的有效方法。
[Abstract]:Objective: to investigate the significance of CT findings in the diagnosis of thyroid nodules. Methods: Ct plain and three phase enhanced CT images of 30 cases of thyroid nodules (38 nodules) confirmed by operation and pathology were retrospectively analyzed. All CT signs were interpreted by two or more senior medical practitioners. Combined with pathological data, the value of CT signs in differentiating benign and malignant thyroid nodules was analyzed. Results: the boundary of 33 benign nodules was clear. There were complete or incomplete enhancement of capsule, solid part of nodular enhancement, dead zone of no enhancement of cyst, 27 time density curves of enhancement were efflux, 6 benign nodules could not accurately measure CT value because of more cystic part and less solid part. It was impossible to type, 4 nodules appeared calcification, the shape of them were speckled, nodular, annular coarse calcification, one case of thyroid multiple nodule had the same appearance in neck 鈪，
