| 目的 探讨甲型H1N1流感肺炎的胸部CT表现及动态变化。 方法 对60例甲型H1N1流感确诊患者进行胸部CT扫描(含HRCT),回顾性分析、比较病变的影像学特点及动态变化并进行半定量CT评分。 结果 甲型H1N1流感胸部CT表现及动态变化特点:①主要表现为片状肺实质渗出病灶,早期和吸收期主要CT表现为磨玻璃密度影;②两肺小叶性或节段性散在分布,以胸膜下和支气管周围多见,下叶较重;③肺组织、胸膜及纵隔受累可同时存在;④病程早期CT评分4.41且逐渐下降,渗出性病灶短期内吸收较快,后期遗留纤维化病变CT评分1.64分。 结论 甲型H1N1流感肺炎的动态胸部CT表现具有一定特征性。熟悉其胸部CT表现有助于该病的诊断、鉴别诊断与疗效观察,但确诊需依靠流行病学史及实验室检查。 |

| Objective To evaluate chest CT appearances and dynamic changes in patients with novel influenza A (H1N1) infection. Methods Sixty patients with confirmed H1N1 received chest CT scans (including HRCT). The imaging characteristics and dynamic changes associated with semiquantitative score were retrospectively analyzed. Results The characteristics of chest CT findings and dynamic changes were as follows: ①Patchy exudation focus of lung parenchyma was the main finding, while ground-glass opacities was the chief CT finding in early stage and absorption stage. ②The lobule and segment shadows of lungs distributed sporadicly, had a predominant subpleural and peribronchial distribution, mostly in lower lungs. ③There was co-existence of involvement of the lungs, pleura and mediastinum. ④CT score in early course of disease was 4.41 and then gradually decreased, the absorption of exudative lesions of lung was quick in a short time. The lesions of lung can be appeared fibrosis at the period of the end and CT score was 1.64. Conclusion There are some radiographic characteristics in influenza H1N1 pneumonia. Getting familiar with chest CT appearances is helpful for its diagnosis and differential diagnosis, but the definite diagnosis is dependent on epidemiology history and laboratory results. |
