The effects of normobaric and hyperbaric oxygenation on MRI signal intensities in -weighted, -weighted and FLAIR images in human brain.

Background: Dissolved oxygen has known paramagnetic effects in magnetic resonance imaging (MRI). The aim of this study was to compare the effects of normobaric oxygenation (NBO) and hyperbaric oxygenation (HBO) on human brain MRI signal intensities.

Patients And Methods: Baseline brain MRI was performed in 17 healthy subjects (mean age 27.
