摘　　要：目的 探讨不同级别甲型H1N1病毒性流感患者的胸部影像学表现,评价其表现对此病分级及预后评估的临床价值.方法 本院确诊的甲型H1N1流感患者286例行胸部X线检查,其中8例行胸部CT平扫,1例危重病例进行预后胸片及CT扫描追踪.对甲型H1N1病毒性流感患者一般病例、重症病例及危重病例的胸部X线和CT表现进行回顾性分析.结果 286例中一般病例263例,其中235例自发病至出院胸部均未出现异常表现,28例最初X 线表现以肺内轻微渗出为主;重症病例13例,其中8例以间质浸润为主,5例以局灶性斑片状高密度影为主;危重病例10例,其中7例以肺实变为主,2例局限性斑片影伴胸腔积液,1例呈毛玻璃样影,1例危重病例预后随诊肺内有纤维条索形成.结论 甲型H1N1病毒性流感患者一般病例肺部表现轻或正常,危、重病例表现为间质浸润和肺实变.Objective To investigate chest radiological imaging characteristics of the influenza A H1N1 patients in different grade and to estimate the value of which in classification and prognosis of this disease. Methods 286 with influenza A H1N1 patients were checked by X-ray , among them, 8 cases were scanned by CT, and 1 critical case underwent both prognosis chest X-ray and CT fol- lowed. All the patients＇ chest X-ray and CT representation were retrospectively analyzed . Results 263 patients were slight cases, among them, 235 cases had no abnormal appearance, and 28 cases had slight innerlungen exudation on X-ray pictures. Among 13 ca- ses of the serious conditions, 8 patients showed lung mesenchyma infiltration, 5 cases showed focal speckle high-density. 10 critical cases presented consolidation of lung （7/10 } , patch shadow density with pleural effusion { 2/10） , ground-glass opacity { 1/10）. One critical patient was found having bands of fibrous tissue during follow-up. Conclusion Most common influenza A H1N1 patients have no abnormal appearances at chest X-ray,while serious and critical cases show mesenchyma infiltration and consolidation of lung.
