Eine MR-Bildgebungsverfahren, um die Verteilung der pulmonalen Durchblutung unter einer Vielzahl von physiologischen Bedingungen zu studieren, in diesem Fall Kontakt mit drei verschiedenen inspiriert Sauerstoffkonzentrationen: Hypoxie, Normoxie und Hyperoxie, beschrieben. Diese Technik nutzt die menschliche Lunge Physiologie Forschungsmethoden in einem MR-Umfeld.
