Fig. 8From: Generation of ventilation/perfusion ratio map in surgical patients by dual-energy CT after xenon inhalation and intravenous contrast mediaChanges in respiratory functions and blood gas parameters before and after resection in patients with thoracoscopic versus thoracotomy resection. a In the whole group we also compared surgical procedure, throracoscopic versus thoracotomy. The changes in respiratory function before and after resection had similar trends. b This trend was also maintained regarding blood gas exchange parameters. * p < 0.05 vs preoperative valuesBack to article page
