En MR-metod för att studera fördelningen av pulmonell blodflöde under olika fysiologiska förhållanden, i detta fall exponering mot tre olika inspirerade syrehalter: hypoxi, normoxia och hyperoxia, beskrivs. Denna teknik utnyttjar människors lungor tekniker fysiologi forskning i en MR-skanning miljö.
