胸部影像检查在甲型H1N1流感诊治中的应用及规范建议

目的探讨规范的胸部影像检查在甲型H1N1流感患者诊治中的应用价值.方法回顾性分析773例甲型H1N1流感患者的胸部X线、CT及高分辨率CT(HRCT)资料。结果 773例患者均接受胸部X线检查,78例接受CT检查,2例接受HRCT检查。胸部X线表现未见明显异常685例,占88.62%(685/773);双肺纹理增多、增粗、模糊等肺间质改变45例,占5.82%(45/773);肺间质改变伴肺门结构模糊28例,占3.62%(28/773);双肺间质改变合并多发斑片状渗出灶15例,占1.94%(15/773)。5例合并胸膜炎(5/773,0.65%)。结论甲型H1N1流感患者胸部影像学表现具有一定特征性,轻症患者X线检查多无明显异常,胸部X线及CT动态复查是了解病情进展的有效方法。

Application and suggestion of standard chest imaging examination in diagnosis and treatment of swine influenza H1N1

Objective To explore the application value of standard chest imaging examination in diagnosis and treatment of patients with swine influenza H1N1. Methods Imaging data including X-ray examination, CT and high resolution CT (HRCT) of 773 swine influenza H1N1 patients were retrospectively analyzed. Results Chest X-ray examination was performed in all 773 cases, as well as CT in 78 cases and HRCT in 2 cases. There were 685 cases (685/773, 88.62%) without obvious abnormal manifestations by X-ray examination. Pulmonary interstitial changes of increased and blurred lung-markings were found in 45 cases (45/773, 5.82%). Pulmonary interstitial changes combined with blurred lung hilum structures in 28 cases (28/773, 3.62%). Pulmonary interstitial changes combined with multiple patchy exudation in 15 cases (15/773, 1.94%). There were 5 cases (5/773, 0.65%) of pleurisy. Conclusion Thoracic imaging findings of swine influenza H1N1 are characteristic, but the majority of mild cases showed no obvious abnormal manifestations. X-ray examination and CT are effective methods to monitor the state of illness.
