摘　　要：目的 探讨肺炎型肺癌在18F-FDG PET/CT显像中的特征,以提高对该病的认识。方法回顾性分析3 7例经病理证实的肺炎型肺癌的临床、病理及18F-FDG PET/CT检查资料,总结其影像学特征,采用单因素方差分析比较不同密度病灶间S UVmax的差异,运用Fishe r确切概率法比较局限性及弥漫性肺炎型肺癌转移发生率的差异。结果 肺炎型肺癌特征性表现为沿肺叶、肺段分布的实变影和/或磨玻璃(GGO)影,以实变与GGO混合病灶(59.5%),弥漫性分布(59.5%)多见,常见的伴随征象有小结节样播散灶(64.9%)、支气管充气征(45.9%)及蜂窝征(32.4%);病灶的不同密度对SUVmax有显著影响(F=6.456,P=0.004),纯实变型SUVmax显著高于纯GGO型SUVmax(P=0.004);弥漫性病例小结节样播散灶的发生率显著高于局限性病例。结论 肺炎型肺癌在18F-FDG PET/CT显像中具有一定的特征,充分认识这些征象对该病的诊断和分期具有指导意义。Objective To investigate the characteristics of pneumonic type lung carcinoma(PTLC)in 18F-FDG PET/CT imaging,and to improve the understanding of the disease.Methods The clinical,pathological and 18F-FDG PET/CT data of 37 cases with pathologically confirmed PTLC were retrospectively analyzed.The imaging features of PTLC were summarized.Univariate analysis of variance was used to compare the difference of SUVmax among lesions with different density,and Fisher exact probability method was used to compare the difference in the incidence of metastasis between localized PTLC and diffuse PTLC.Results PTLC in 18F-FDG PET/CT imaging was characterized by consolidation and/or ground glass opacity(GGO)distributed along the lung lobes or segments,with mixed lesions of consolidation and GGO(59.5%)and diffuse distribution(59.5%)dominantly,and often accompanied by nodular spread(64.9%),air bronchial sign(45.9%)and honeycomb sign(32.4%).Diffe rent focal density significa ntly affected SUVmax of the lesion(F=6.456,P=0.004),and SUVmax of pure consolidation type was significantly higher than that of pure GGO type(P=0.004).The incidence of nodular spread in diffuse cases was significantly higher than that in localized cases.Conclusion PTLC has some characteristics in18F-FDG PET/CT imaging,and full understanding of these signs provides guiding significance for the diagnosis and staging of the disease.
