[Differential spirometry and computerized pulmonary ventilation- perfusion scintiphotography as preoperative...

With purposes of a better knowledge of the respiratory function, and for a more and more exact postoperative functional prognosis, the authors considered the results obtained by the differential bronchospirometry and the pulmonary ventilation-perfusion imaging. Through the study of 10 patients, susceptible of operations for lung extirpation, they could so evaluate the reliability and usefulness of said two functional investigations, which can integrate and complete each other.
