摘　　要：目的通过多层螺旋CT(MSCT)的后处理技术、肺结节分析功能深入分析肺炎型肺癌与局灶性肺炎的各种征象,结合CT导引下穿刺活检的病理结果进行对比回顾性研究,探讨肺炎型肺癌的MSCT诊断与鉴别诊断价值。方法 45例肺炎型肺癌和50例局灶性肺炎患者均行MSCT全肺容积扫描,再经高分辨率CT(HRCT)、多平面重建(MPR)及Lung Care软件结节分析,最终根据取得的病理结果加以回顾性研究并做χ2检验进行统计学分析。结果孤立肺炎型肺癌在短细毛刺、血管集束征、胸膜凹陷征、支气管充气征以及Lung Care软件结节分析瘤体显示方面明显高于局灶性肺炎(P<0.01)。结论通过MSCT的后处理技术、肺结节分析功能能对病理基础不同的肺炎型肺癌与局灶性肺炎提供较明确的诊断与鉴别诊断依据,为临床及早准确治疗提供依据。Objective Through the MSCT post-processing technique and the lung nodules features analysis, pneumonia-lung cancer and focal pneumonia combined with pathological esuts of biopsy under CT guidance were compared retrospectively. MSCT＇s diagnosis and differential diagnosis value of lung cancer were discussed in this pa per. Methods Forty-five cases of pneumonia-lung cancer patients and 50 cases of focal pneumonia were performed. MSCT scan the whole lung volume, then through high resolution CT（HRCT）, multi-planar reformation（MPR） and Lung Care software analyzed lung nodules finally according to the pathological results were retrospectively studied and chi- square test for statistical analysis. Results Pneumonia-lung cancer in the short fine burrs sign, the vessel conver gence sign, the pleural indentation sign, the aerial bronchogram and the Lung Care software analyzing tumor results significantly higher than the focal pneumonia（P〈O.01 ）. Conclusion By MSCT post-processing technique and analysis to pathological lung nodules in different type of pneumonia-lung eancer, it provides a clear diagnosis and differential diagnosis for focal pneumonia, and provides the basis of accurate treatment for the clinical work as early as possible.
