Non-contrast based assessment of the pulmonary function using MRI remains challenging. We propose a novel post-processing method based on the Wavelet analysis to retrieve information about pulmonary perfusion and ventilation. The method utilizes rapid acquisition of time-resolved MR-data using a 2D Steady-State Free Precession sequence implemented on a 1.5 T whole-body MR-scanner. Wavelet transform allows for a robust analysis of non-stationary physiological signals (respiratory/cardiac cycles). The aim of this study was to show feasibility of the proposed approach.
