“…For the three sampling cases, mean ADC/L(m) values were not significantly different (all p > 0.5); ADC/L(m) values were significantly different for the COPD subgroup (0.08 cm(2)s(−1)/580 µm, AF = 3; all p < 0.001) as compared to never-smokers (0.05 cm(2)s(−1)/300 µm, AF = 3). For never-smokers, mean differences of 7%/7% and 10%/7% were observed between fully sampled and retrospectively undersampled (AF = 2/AF = 3) ADC and L(m) values, respectively. …”
