Thirty-nine Xenon-133 ventilation and perfusion studies in 36 patients with bronchiectasis were analyzed retrospectively. These patients showed a marked reduction in ventilation with a less severe reduction in pulmonary arterial perfusion, resulting in areas of low ventilation-perfusion ratios. In those patients with bronchographic confirmation, xenon studies had greater sensitivity (0.89) than the chest radiographs (0.71). Where both the radiograph and the scan are normal, bronchiectasis is virtually excluded; therefore bronchography is not indicated.
