摘要 目的:评价MPR对肺癌的诊断价值。方法:搜集经CT、临床、手术、活检病理证实肺癌患者80例,其中中心型肺癌42例,周围型肺癌38例。进行薄层横断面与MPR图像肺癌基本征象显示的对照研究。结果:MPR图像与横断面在显示小泡征、支气管充气征、空洞方面无显著性差异;在显示分叶征、棘突征、毛刺征,支气管血管集束征方面具有显著性差别;在显示胸膜凹陷征、病灶侧胸膜改变不具有统计学意义。结论:MPR图像有利于全面显示肺癌征象,提高了肺癌的诊断准确率。 Objective:To evaluate the value of the images of MPR in the diagnosis of lung cancer. Methods: 80 cases with lung cancer CT,clinically,operatively,pathologically proved were collected,including 42 cases with central type,38 cases with peripheral type. The images of MSCT were compared with axial thin - slice images on the characteristic signs of lung cancer. Results:MPR and axial scanning were not markedly different in showing the signs of little vacuole,air-bronchial and cavities,but markedly different in showing the signs of lobulation, spine,piculation and bronchi- vessel convergence. MPR and axial scanning had not statistics significance in showing the signs of pleura indentation or the change of pleura on the side of focus. Conclusion : MPR is helpful to showing the overall signs of lung cancer, which improved the diagnostic accuracy of lung cancer.
