Nine children between the ages of seven to 12 were studied. All of these children had an acute unilateral pneumonia caused by Mycoplasma pneumoniae. Regional pulmonary function studies were performed with the aid of an Xe133 radio-spirometry. It was shown with this technique that the ventilation of the infected part was more reduced than the perfusion during the acute stage. Fourteen to 22 days after the onset of the disease three children had normal chest X-rays but abnormalities of the pulmonary function tests. In one child this abnormal function persisted at the third follow-up some months later. By the use of regional pulmonary function studies subtle abnormalities can be observed which would normally be overlooked when examining the pulmonary function of both lungs.
对9名7至12岁的儿童进行了研究。所有这些儿童均患有由肺炎支原体引起的急性单侧肺炎。借助Xe133放射性肺量计进行了局部肺功能研究。用该技术显示，在急性期，感染部位的通气比灌注减少得更多。发病后14至22天，3名儿童的胸部X光片正常，但肺功能测试异常。在一名儿童中，这种异常功能在几个月后的第三次随访时仍然存在。通过使用局部肺功能研究，可以观察到一些细微的异常，而在检查双肺肺功能时这些异常通常会被忽略。
