Claim 8:
9. The method of claim 1, further comprising obtaining gas exchange 129Xe Magnetic Resonance Imaging (MRI images of the lung or lungs of the subject and electronically calculating RBC transfer defect percentage, ventilation defect percentage and barrier defect percentage and high barrier uptake percentage from the gas exchange 129Xe MRI images,
wherein when the corrected RBC amplitude oscillations are at 7.9% or less, the subject is diagnosed as likely having pre-capillary pulmonary hypertension, and
wherein when the corrected RBC amplitude oscillations are at least 1.5X larger than a healthy cohort and/or the high barrier uptake percentage is at or above 20%, the subject is diagnosed as likely having Idiopathic pulmonary fibrosis (IPF).
