数字X射线影像诊断在小儿肺炎支原体肺炎中的应用价值

The Application Value of Digital X-Ray Imaging Diagnosis in Children with Mycoplasma Pneumoniae Pneumonia

目的:探索数字X射线影像诊断在小儿肺炎支原体肺炎中的应用价值。方法:回顾性分析的86例疑似肺炎支原体肺炎患儿均在2022年4月~2023年5月收治,均进行传统X射线和数字X射线摄影检查,以临床确诊结果为金标准,比较两种检查方式准确率,经ROC曲线模型分析两种诊断方式效能。结果:86例疑似肺炎支原体肺炎,经后期确诊的有73例,共发现96处病灶。结果显示,阳性和阴性组的影像学分型存在统计学差异性(P<0.05),数字X射线对影像学分型准确率高于传统X射线(P<0.05),数字X射线整体影像质量优于传统X射线(P<0.05)。与确诊比较,传统X射线诊断准确率77.91%(67/86),数字X射线诊断准确率95.35%(82/86),两两比较中,数字X射线与传统X射线比较有差异(χ^(2)=9.125,P<0.001)。经ROC曲线分析,传统X射线、数字X射线诊断肺炎支原体肺炎的AUC分别为0.743、0.941。结论:数字X射线影像诊断在小儿肺炎支原体肺炎中具有较高效能,可为临床诊疗提供科学依据。

Objective:To explore the application value of digital X-ray imaging diagnosis in the diagnosis of mycoplasma pneumoniae pneumonia in children.Methods:A retrospective analysis was conducted on 86 suspected children with Mycoplasma pneumoniae pneumonia who were admitted from April 2022 to May 2023.Both traditional X-ray and digital X-ray examinations were performed,with clinical diagnosis results as the gold standard.The accuracy of the two examination methods was compared,and the efficacy of the two diagnostic methods was analyzed using the ROC curve model.Results:Of the 86 suspected cases of mycoplasma pneumoniae pneumonia,73 were diagnosed later and a total of 96 lesions were found.The results showed that there was a statistical difference in the imaging classification between the positive and negative groups(P<0.05).The accuracy of digital X-ray for imaging classification was higher than that of traditional X-ray(P<0.05),and the overall image quality of digital X-ray was better than that of traditional X-ray(P<0.05).Compared with confirmed diagnosis,the accuracy rate of traditional X-ray diagnosis is 77.91%(67/86),and the accuracy rate of digital X-ray diagnosis is 95.35%(82/86).In pairwise comparison,digital X-ray is compared with traditional X-ray(χ^(2)=9.125,P<0.001).By receiver operating characteristic analysis,AUC of traditional X-ray and digital X-ray diagnosis of mycoplasma pneumoniae pneumonia were 0.743 and 0.941 respectively.Conclusion:Digital X-ray imaging diagnosis has high efficacy in the diagnosis of mycoplasma pneumoniae pneumonia in children,and can provide scientific basis for clinical diagnosis and treatment.
