结节性甲状腺肿的MSCT诊断

Diagnostic value of MSCT in nodular goiter

目的:探讨结节性甲状腺肿的MSCT诊断价值。方法:回顾分析经手术病理证实为结节性甲状腺肿的20例患者的临床及CT资料,主要观察病灶的部位、数目、大小、形态、边界、密度、与周围组织结构关系以及强化方式等影像学表现,并与病理结果进行对照。结果:20例病例中,多结节型(数目≥2)9例,单结节型11例,边界清晰8例,边界模糊12例,密度均匀5例,密度不均15例,9例合并囊变,8例合并钙化,钙化为粗点状、弧形或环状钙化,增强扫描不同程度强化。结论:MSCT平扫、结合增强及图像重建技术,能完整显示结节性甲状腺肿的内部特征及与周围组织结构的关系,解剖结构清晰,定位准确。

Objective:To analyze the diagnostic value of MSCT in nodular goiter.Methods:the clinical and CT data of 20 patients with nodular goiter confirmed by surgery and pathology were retrospectively analyzed,and the imaging manifestations such as location,number,size,shape,boundary,density,relationship with surrounding tissue structure and enhancement mode were mainly observed,and compared with the pathological results.Results:among the 20 cases,there were 9 cases of polynodular type(number≥2),11 cases of single nodular type,8 cases with clear boundary,12 cases with fuzzy boundary,5 cases with uniform density,15 cases with uneven density,9 cases with cystic degeneration,and 8 cases with calcification.Calcification was coarse-dotted,arc-shaped or ring-shaped calcification.Conclusion:MSCT plain scan,combined with enhancement and image reconstruction technology can completely display the internal characteristics of nodular goiter and its relationship with surrounding tissue structure,with clear anatomical structure,and accurate positioning.
