摘　　要：目的 分析学龄期支原体肺炎(MPP)患儿高分辨率X线计算机断层摄影(HRCT)影像学特征与肺功能的关系。方法 回顾性收集2021年12月~2023年12月于本院治疗的60例学龄期MPP患儿的临床资料,所有患儿均实施H RCT和肺功能检查,分析其HRCT影像学特征,并比较不同HRCT影像学特征学龄期MPP患儿肺功能指标水平[用力肺活量(FVC)、50%用力肺活量时的用力呼气流量(FEF50)、1秒用力呼气容积(FEV1)、每分钟最大自主通气量(MVV)]。结果经HRCT检查,60例学龄期MPP患儿中,51.67%(31/60)患儿病变部位在右肺,65.00%(39/60)患儿存在肺实变,其中小叶性5例,节段性11例,大叶性23例;75.00%(45/60)患儿存在小气道改变,其中树芽征24例,小叶中心结节21例;8.33%(5/60)患儿存在磨玻璃影;26.67%(16/60)患儿存在淋巴结肿大;8.33%(5/60)患儿存在胸腔积液;63.33%(38/60)患儿存在支气管壁增厚。存在肺实变的学龄期M PP患儿FVC、FEF50、FEV1、MVV水平显著低于未发生肺实变的学龄期MPP患儿,且不同程度肺实变的学龄期MPP患儿FVC、FEF50、FEV1、MW水平存在显著性差异(P<0.05)。发生小气道改变、胸腔积液的学龄期MPP患儿FVC、FEF50、FEV1、MVV水平均分别低于未发生小气道改变、胸腔积液的学龄期MPP患儿(P<0.05)。结论 HRCT可清楚显示学龄期MPP患儿病变位置与范围,且肺实质改变、小气道改变等影像学特征与其肺功能存在一定关系。Objective To analyze the relationship between high-resolution X-ray computed tomography(HRCT)imaging cha racteristics and pulmonary function in school-age children with mycoplasma pneumoniae pneumonia(MPP).Methods The clinical data of 60 school-age children with MPP who were treated in the hospital were retrospectively collected from December 2021 to December 2023.All children ca rried out H RCT and pulmonary function test.The H RCT imaging cha racteristics were analyzed,and the levels of pulmonary function indicators[forced vital ca pacity(FVC),forced expiratory flow at 50%forced vital capacity(FEF50),forced expiratory volume in one second(FEV1),maximum voluntary ventilation per minute(MVV)]were compared among school-age MPP children with different HRC imaging characteristics.Results After HRCT examination,51.67%(31/60)of 60 school-age children with MPP had lesions in the right lung,and 65.00%(39/60)had lu ng consolidation,including 5 lobula r type,11 segmental type and 23 lobar type.75.00%(45/60)of the children had small airway changes,including 24 cases of tree-in-bud sign and 21 cases of central lobula r nodule.8.33%(5/60)had ground glass shadow,26.67%(16/60)had lymph node enlargement,8.33%(5/60)had pleural effusion,and63.33%(38/60)had bronchial wall thickening.The FVC,FEF50,FEV1 and MVV in school-age MPP children with pulmonary consolidation were significantly lower than those in MPP children without pulmonary consolidation,and there were significa nt differences in FVC,FEF50,FEV1 and MVV among children with different degrees of pulmonary consolidation(P<0.05).The FVC,FEF50,FEV1 and MVV in school-age MPP children with small airway changes and pleural effusion were lower than those in MPP children without small airway changes and pleural effusion respectively(P<0.05).Conclusion HRCT can clea rly show the location and ra nge of lesions in school-age children with MPP,and there is a certain relationship between imaging characteristics such as pulmonary parenchymal changes and small airway changes and pulmonary
