Claim One:
1. An MRI scanner system, comprising: a xenon alveolar-capillary transfer (XACT) imaging module; and an MRI scanner comprising the XACT imaging module or in communication with the XACT imaging module and an MRI receiver configured to receive (i) dissolved phase hyperpolarized 129 Xe red blood cell (RBC) signal data of an RBC compartment of a gas exchange region of at least one lung of a patient at a first resonance and (ii) dissolved phase hyperpolarized 129 Xe blood-gas barrier compartment signal data of the gas exchange region of the at least one lung of the patient at a different second resonance, wherein the XACT imaging module directs the MRI scanner to an MRI scanner frequency of a 129 Xe dissolved phase imaging mode for xenon alveolar-capillary transfer imaging to receive-the hyperpolarized 129 Xe dissolved phase signal data of the blood-gas barrier compartment and the RBC compartment of the gas exchange region of the at least one lung, and wherein the MRI scanner frequency for the 129 Xe dissolved phase imaging excites both the first and second resonances but not a gas phase resonance of the hyperpolarized 129 Xe.
