A case study of simultaneous measurement of p0, R and ADC with HP 3He MRI on a COPD patient. In the selected region-of-interest (white square box), the ADC is 29% higher while R is 61% lower than the corresponding global average values. A correlation between the two parameters suggests that in the region where lung tissue was destroyed by COPD, the oxygen exchange efficiency was also reduced.
