To compare quantitative fractional ventilation measurements from multiple breath washout imaging (MBW‐I) using hyperpolarized 3He with both spoiled gradient echo (SPGR) and balanced steady‐state free precession (bSSFP) three‐dimensional (3D) pulse sequences and to evaluate the feasibility of MBW‐I with hyperpolarized 129Xe.
