Brief Summary

The overall objective outlined in this study is to determine how pulmonary vascular remodeling in PAH at a cellular and pathological level is associated with changes in gas exchange physiology and hemodynamics (monitored with 129Xe MRI/MRS) and how these signals change with disease progression or treatment.
