A male infant, with bronchopulmonary dysplasia and ventilator dependence, had lung ventilation (Xe-133 gas) and perfusion (Tc-99m MAA) imaging performed. The examination revealed a region that was ventilated but not perfused (mismatch) and a separate area that was perfused but not ventilated (reverse mismatch). The basis of both abnormalities is suspected to be related to bronchopulmonary dysplasia, atelectasis and/or mechanical ventilation. Ventilation/perfusion mismatches and reverse mismatches can occur in the same patient.
一名患有支气管肺发育不良且依赖呼吸机的男婴接受了肺通气（Xe - 133气体）和灌注（Tc - 99m MAA）显像检查。检查发现一个区域通气但无灌注（不匹配），以及另一个单独区域灌注但无通气（反向不匹配）。这两种异常情况的原因怀疑与支气管肺发育不良、肺不张和/或机械通气有关。通气/灌注不匹配和反向不匹配可出现在同一患者身上。
