目的分析结节性甲状腺肿的MSCT表现,旨在提高对结节性甲状腺肿的认识。方法回顾性分析28例经手术证实为结节性甲状腺肿的MSCT表现。结果其主要CT征象为(1)病灶呈多发96%(27/28)低密度灶,(2)病变多合并囊变78.5%(22/28),钙化53.7%(15/28),同时囊变及钙化者亦多见42.8%(12/28),(3)增强扫描呈轻度及中度强化,坏死囊变区无强化,强化方式多样且多种强化方式可位于同一受累甲状腺肿。结论结节性甲状腺肿MSCT表现具有一定特征性,分析其影像学特点,有助于提高其诊断准确率。
Objective To analyze the performance of nodular goiter in order to improve the understanding of nodular goiter. Methods A retrospective analysis of 28 cases of nodular goiter confirmed by MSCT findings. Results The main CT findings were (1) 96% (27/28) with low density lesions, (2) 78.5% (22/28) lesions with calcification and 53.7% (15/28) calcifications, Change and calcification were also more common in 42.8% (12/28), (3) enhanced scan showed mild and moderate enhancement, necrosis of cystic area without strengthening, strengthening and diverse ways and a variety of strengthening methods can be located in the same involvement of goiter. Conclusion The performance of nodular goiter has some characteristics of MSCT, analyze its imaging features, help to improve the diagnostic accuracy.
