摘　　要：目的：探讨螺旋CT薄层重建技术对肺错构瘤的诊断价值。方法分析21例经手术病理证实的肺错构瘤患者,先行胸部常规CT扫描,再行CT薄层重建。观察2种图像上病灶的边缘特征及内部特征,将观察结果行卡方检验,以P〈0.05为差异显著标准。结果常规CT与薄层重建图像比较：①分叶征的显示率相同,均为12例（57.1%）。②钙化的显示率相同,均为9例（42.9%）。③脂肪的显示率分别为3例（14.3%）和9例（42.9%）,差异有统计学意义（χ2=4.200,P〈0.05）。④常规CT与薄层重建对血管穿过征的显示率分别为3例（14.3%）和10（47.6%）,差异有统计学意义（χ2=5.459,P〈0.05）。结论 CT薄层重建较常规 CT能更好地显示肺错构瘤的内部特征,提高诊断正确率。Objective To investigate the diagnostic significance of thin layer reconstruction with spiral CT on the pulmonary hamartoma. Methods Accepted both routine CT examination and thin layer construction,2 1 pulmonary hamartoma cases confirmed by pathology were analyzed retrospectively.The margin and inner features of the lesions were observed and recorded.Significant analysis was performed by using SPSS17.0 Pearson chi-square test and Fisher exact test,with P〈0.05 as the significant difference criterion.Results Comparison of the display rates by routine CT and thin layer reconstruction：①the same display rate of lobulation were 57.1%（12/21）;②the same display rate of calcification were 42.9% （9/21）;③the display rates of fat density were 14.3%（3/21）by routine CT and 42.9% （9/21）by thin layer reconstruction.The difference was statistically significant （χ2=4.200,P〈0.05）;④the display rates of blood vessel throughing were 14.3%（3/21）by routine CT and 47.6% （10/21）by thin layer reconstruction.The difference was statistically significant （χ2=5.459,P〈0.05）.Conclusion Displaying the inner features of pulmonary hamartoma better than routine CT,the thin layer reconstruction can improve the diagnostic accuracy significantly.
