Abstract:
Objective To observe CT findings of mycoplasma pneumoniae pneumonia(MPP)in children.Methods A total of 85 MPP children confirmed by mycoplasma pneumoniae nucleic acid test were retrospectively collected.Chest CT manifestations of MPP were analyzed,and artificial intelligence pneumonia CT image-assisted diagnostic analysis software was used to quantify lesion volume(LV),percentage of lesion LV in total lung volume(LV％)and CT value,and the correlations of quantitative CT parameters with clinical laboratory indicators were explored.Results The main CT manifestations of MPP in children included thickened bronchial wall(78/85,91.76％),tree bud sign(70/85,82.35％),large mass compaction(39/85,45.88％),bronchial occlusion(29/85,34.12％),air bronchial sign(25/85,29.41％),acinar nodules(23/85,27.06％),consolidation along the bronchus(21/85,24.71％),cotton ball sign(19/85,22.35％),tree fog sign(15/85,17.65％)and atelectasis(14/85,16.47％).The median LV of MPP was 50.73(26.38,85.90)cm3,the median LV％was 3.10％(1.60％,5.70％)and the median CT value was-422.61(-479.46,-343.76)HU.MPP LV was positively correlated with serum sialic acid,C reactive protein(CRP),D-dimer,fibrin degradation products(FDP)and fibrinogen(Fib)(rs=0.232-0.400),while LV％was positively correlated with serum sialic acid,D-dimer and FDP(rs=0.349-0.439).There was a positive correlation between CT value and CRP(rs=0.288).Conclusion CT findings of MPP in children had certain characteristics.Combining with laboratory examinations was conducive to clinical diagnosis,monitoring condition and evaluating therapeutic efficacy of MPP in children.
