Imaging and pathology from case 1. A, Representative axial computed tomography image demonstrating no significant abnormalities. B, ¹²⁹Xe magnetic resonance imaging of ventilation demonstrating no significant abnormalities. C, ¹²⁹Xe spectroscopy showing a severe decrease in xenon signal in red blood cells (RBCs) relative to barrier tissue (left) and representative single-breath gas exchange images showing homogeneous gas and barrier signal while ¹²⁹Xe transfer to RBCs contains severe focal abnormalities (right). D, Pathology demonstrating pulmonary venoocclusive disease.
