摘要
目的比较分析微小甲状腺乳头状癌(PMCT)及结节性甲状腺肿(NG)的多层螺旋CT(multi-slice spiral CT,MSCT)征象,并探讨MSCT鉴别二者的价值。方法回顾性分析病理证实的34例PMCT及46例NG的MSCT表现,从结节的形态及边缘、有无钙化、钙化的部位及形态、增强后结节边缘及轮廓改变、有无淋巴结增大方面,分析PMCT瘤体与NG结节的MSCT特征,用SPSS19.0软件进行统计学处理。结果 PMCT与NG组间结节的边缘、钙化部位、钙化形态、增强后结节边缘及轮廓改变的比较具有显著性差异(P<0.05);结节的形态、有无钙化、有无淋巴结增大的比较无显著性差异(P>0.05)。结论综合分析PMCT与NG结节的各种MSCT征象,有助于PMCT与NG的鉴别诊断,并提高PMCT的检出率。
Objective To analyze and compare the multi-slice spiral CT（MSCT） appearances of papillary microcarcinoma of thyroid （PMCT） and nodular goiter （NG）, and to investigate the value of MSCT in the identification of them. Methods MSCT manifestations in 34 cases of PMCT and 46 cases of NG confirmed by pathology were retrospectively analyzed, the MSCT features of PMCT tumor body and NG nodules including shape and edge, with or without calcification, location and shape of calcification, edge continuity and contour change of enhanced nodules, with or without lymph node enlargement aspect were analyzed, using SPSS 19.0 software for statistical analysis. Results There were significant differences between PMCT and NG group in edge of nodules, location and shape of calcification, edge continuity and contour change of enhanced nodules （P〈0.05）. The comparison of the shape of nodules, with or without calcification or lymph node enlargement between them has no significant difference （P〉0.05）. Conclusion Comprehensively analyze the MSCT features of PMCT tumor body and NG nodules was helpful for antidiastole between PMCT and NG, and to improve the detection rate of PMCT.
