The aim of this work was the implementation of combined spirometric and ³¹P MRS measurements. We adapted a commercial gas exchange system by extending the gas sampling line from 3 m to 5 m to perform acquisitions of pulmonary ventilation in a MR scanner. Calibration measurements showed changes in an appropriate range in the delay- and response time.
