摘　　要：目的 探讨高原肺水肿（HAPE）胸部X线征象特点及半定量分析方法的临床应用。方法 回顾性分析152例HAPE的胸片，根据病变严重程度及分布范围，对HAPE进行评分，计算各肺野HAPE阳性率。按不同肺野、年龄、性别及心胸比（CTR）分组，比较各组HAPE评分及各肺野HAPE阳性率的差异。结果 右肺下野HAPE评分为3.45，HAPE阳性率为95.4%，二者均显著高于其余肺野。HAPE评分组间对比结果显示：≥40岁组显著高于＜40岁组（10.95 vs 9.44，P=0.002）、女性组显著高于男性组（11.65 vs 9.99，P=0.029）、CTR＞0.5组显著高于 CTR≤0.5组（10.77 vs 9.25，P=0.002）。结论 基于X线征象的半定量分析方法可以反映HAPE的严重程度及病变分布特点，CTR异常者及40岁以上的女性患者疾病影像学表现较重。Objective To investigate the characteristics and the clinical value of semi-quantitative analysis on chest radiography of high altitude pulmonary edema （HAPE）.Methods The chest radiography film of 152 patients with HAPE were analyzed retrospectively. HAPE scores were calculated based on the disease severity and distribution range,and the positive rate of HAPE was calculated in every lung fields. The patients were divided into to the different groups according to the lung fields,age,gender,and cardiothoracic ratio （CTR）.The HAPE scores and the positive rates were compared between the different groups.Results The HAPE score was 3.45 and the positive rate was 95.4% in the right lower lung field,which were significant higher than those in the other fields. The HAPE scores were significantly higher in the group ≥40 age than in the group〈40 age （ 10.95 vs 9.44,P = 0.002）, significantly higher in the female patients than in the male patients （11.65 vs 9.99,P=0.029） ,and significantly higher in the group with CTR2〉0.5 than in the group with CTR≤0.5（10.77 vs 9.25,P = 0.002） ,respectively.Conclusion The semi-quantitative analysis based on the chest radiography could display the severity and distribution range of HAPE. The disease was more severe in the patients with abnormal CTR and the female over 40 years old.
