PURPOSE: Multi-b diffusion-weighted hyperpolarized inhaled-gas MRI provides imaging biomarkers of terminal airspace enlargement including ADC and mean linear intercept (L
METHODS: We evaluated multi-b (0, 12, 20, 30, and 45.5 s/cm
RESULTS: For the HV subgroup, mean differences of 5%, 2%, and 8% were observed between fully sampled and undersampled k-space for ADC, L
CONCLUSIONS: Accelerated multi-b diffusion-weighted
