Abstract：Objective To analyze the diagnostic value of CT for mycoplasma pneumoniae pneumonia(MPP)in children.Methods A retrospective analysis was conducted on the clinical data of 100 suspected MPP patients admitted to our hospital from June 2020 to November 2022.Pathogenic tests and CT examinations were conducted,and the final results of the pathogenic tests were used as the gold standard to evaluate the diagnostic efficacy of CT examinations for MPP.At the same time,the manifes-tations of the patients during CT examinations and changes in CT images before and after treatment were summarized.Results Pathogenic examination found 88 positive cases and 12 negative cases;CT examination found 86 cases positive and 14 cases negative.The diagnostic accuracy,sensitivity,and specificity of CT examination were 96.00％,96.59％,and 91.67％respectively.Among 86 patients with positive CT results,88.37％had unilateral lobar lesions in terms of lesion distribution;The proportion of bilateral lung lobe lesions was 11.63％.The proportion distributed in the right upper lobe,right middle lobe,right lower lobe,left upper lobe,and left lower lobe was 29.07％,26.74％,34.88％,11.63％and 9.30％respectively.The main CT features of the lesion location were extensive patchy shadows,patchy shadows,increased lung markings,striped shadows,and ground glass shadows,ac-counting for 87.21％,38.37％,33.72％,19.77％,and 15.12％respectively;In terms of other manifestations of the lungs,the thick-ening of bronchial tube walls,enlargement of hilar and mediastinal lymph nodes,and pleural effusion accounting for 79.07％,11.63％and 11.63％respectively.Conclusion CT examination can clearly present the pulmonary lesions in children with MPP,which has a high diagnostic efficiency and can provide important reference for evaluating the condition of the child.
