摘要
目的探究重症肺炎患者的高分辨率CT(HRCT)图像特征及其诊断价值。方法回顾性分析我院2021年5月至2023年4月收治的重症肺炎患者31例和同期65例普通肺炎患者的临床资料,分别纳入重症组和非重症组,均进行HRCT检查,比较两组一般资料病变范围和HRCT图像特征,ROC曲线分析HRCT对重症肺炎的诊断价值。结果重症组患者发热、气喘、意识/定向障碍症状发生率,白细胞计数、中性粒细胞比率、C反应蛋白水平,医院获得性感染肺炎率,合并高血压病、心脑血管疾病、糖尿病以及吸烟史率均高于非重症组(P<0.05);重症组病变肺段15~18个的患者最多,23例(74.19%),其次为13~15个(12.90%),非重症组病变肺段7~12个患者最多,29例(44.62%),其次为13~15个(26.15%),2组病变范围分布差异有统计学意义(P<0.05);重证组患者小叶间隔增厚、索条影、淋巴结增大、淋巴结钙化、实性结节、胸膜增厚、胸腔积液、心包腔积液、肺气囊、气胸发生率均高于非重证组(P<0.05);索条影、淋巴结增大、淋巴结钙化、胸膜增厚、胸腔积液、心包腔积液、肺气囊、气胸等HRCT图像特征诊断重症肺炎的AUC分别为0.796、0.736、0.605、0.720、0.687、0.621、0.573、0.565(P<0.05)。结论HRCT图像特征诊断重症肺炎的特异性较高,可为临床诊断提供参考。
Objective To explore the imaging characteristics and diagnostic value of high resolution CT(HRCT)in patients with severe pneumonia.Methods The clinical data of 31 patients with severe pneumonia and 65 patients with common pneumonia in our hospital were retrospectively analyzed from May 2021 to April 2023,and the above patients were included in severe group and non-severe group respectively.All patients underwent HRCT examination.The general data,lesion range and HRCT imaging characteristics were compared between both groups.ROC curve was used to analyze the diagnostic value of HRCT on severe pneumonia.Results The incidence rates of fever,asthma and consciousness/orientation disorder symptoms,white blood cell count,neutrophil ratio,C-reactive protein,hospital-acquired pneumonia rate,hypertension,cardiovascular and cerebrovascular diseases,diabetes mellitus and smoking history in severe group were higher than those in non-severe group(P<0.05).There were 23 patients(74.19%)with 15-18 lung segments in severe group,followed by 13-15(12.90%).There were 29 patients(44.62%)with 7-12 lung segments in non-severe group,followed by 13-15(26.15%).There was a statistically significant difference in the distribution of lesion range between the two groups(P<0.05).The incidence rates of interlobular septal thickening,strip shadow,lymph node enlargement,lymph node calcification,solid nodules,pleural thickening,pleural effusion,pericardial effusion,pulmonary air sac and pneumothorax were higher in severe group than those in non-severe group(P<0.05).The AUCs of HRCT imaging characteristics such as strip shadow,lymph node enlargement,lymph node calcification,pleural thickening,pleural effusion,pericardial effusion,pulmonary air sac and pneumothorax in the diagnosis of severe pneumonia were 0.796,0.736,0.605,0.720,0.687,0.621,0.573 and 0.565 respectively(P<0.05).Conclusion HRCT imaging characteristics have high specificity in the diagnosis of severe pneumonia,and can provide reference for clinical diagnosis.
