目的分析甲型H1N1流感肺炎的肺CT特点及其与临床转归相关性。方法将73例甲流肺炎患者分为呼吸衰竭组和非呼吸衰竭组,比较两组胸部影像学的差异及影像学严重程度与临床转归的相关性。结果 73例患者中,呼吸衰竭组32例,非呼吸衰竭组41例。两组患者胸部影像学比较病变形态差别不大,但病变范围上有明显差别,呼吸衰竭组患者病变范围大于非呼吸衰竭组。结论影像学严重程度可以作为判断甲型H1N1流感病情严重程度和预后的指标。
Objective To analyze the characteristics of pulmonary CT of Influenza A (H1N1) pneumonia and its correlation with clinical outcome. Methods Seventy-three patients with influenza A were divided into respiratory failure group and non-respiratory failure group. The difference of thoracic imaging and the correlation between the severity of imaging and clinical outcome were compared between the two groups. Results Among the 73 patients, 32 cases were respiratory failure and 41 cases were non-respiratory failure. There was no significant difference between the two groups in the morphology of chest imaging, but there was a significant difference in the extent of the lesion. The extent of lesion in patients with respiratory failure was greater than that in non-respiratory failure group. Conclusion The severity of imaging can be used as an indicator to judge the severity and prognosis of Influenza A (H1N1).
