【摘要】：目的:探討數(shù)字X線胸部攝影對(duì)小兒肺炎支原體肺炎的診斷價(jià)值。方法:對(duì)41例血清IgM抗體滴度升高4倍以上的患兒的初次胸部X線平片影像表現(xiàn)進(jìn)行回顧性分析。結(jié)果:37例(90.3%)顯示段、葉性分布實(shí)變影,8例(19.5%)顯示結(jié)節(jié)樣小葉氣腔實(shí)變,19例(46.3%)顯示支氣管血管束周圍浸潤(rùn)。4例(9.7%)病變累及雙肺,30例(73.2%)累及下肺野。第2次抗體滴度≥1280的患兒肺內(nèi)病變累及范圍大于第2次抗體滴度≤640的患兒(χ2=8.789,P=0.003)。結(jié)論:葉段分布?xì)馇粚?shí)變、支氣管血管束周圍浸潤(rùn)是小兒肺炎支原體肺炎最常見的胸部X線影像表現(xiàn),結(jié)節(jié)樣小葉中心氣腔實(shí)變顯示率較低。肺炎支原體抗體滴度升高程度可能與肺內(nèi)病變的嚴(yán)重程度有關(guān)。
[Abstract]:Objective: to investigate the diagnostic value of digital X-ray chest radiography for mycoplasma pneumoniae pneumonia in children. Methods: the first chest X-ray findings of 41 children whose serum IgM antibody titers increased 4 times or more were analyzed retrospectively. Results 37 cases (90.3%) showed segment, 8 cases (19.5%) showed nodular lobule lumen consolidation, 4 cases (9.7%) showed infiltration around the bronchovascular bundle, 30 cases (73.2%) involved the lower lung field. The extent of lung involvement in children with second antibody titer 鈮，
