Figure 3:

Graphs of xenon 129 MR spectroscopy results in participant with nonspecific interstitial pneumonia (NSIP) (woman, age 67 years; dashed orange line) and healthy control participant (man, age 63 years; solid orange line). Difference in red blood cell (RBC) and barrier peaks leading to reduced RBC-to-barrier ratio is clearly visible in participant with NSIP. Also note reduced chemical (Chem.) shift in RBC peak and increased RBC amplitude and chemical shift oscillations (Osc.) associated with cardiac cycle in participant with NSIP.
