We have build an MR imaging compatible pressure chamber
system for use in basic barometrical research.
Relaxation times (T1 and T2) have been measured during
hyperbaric oxygen, helium, and nitrogen (relevant in
diving applications) exposure (1-10 ATA) of
liquid-phantoms consisting of manganese or gadolinium
enriched water or olive oil. Molecular oxygen is
paramagnetic and can be used as a MRI contrast through
dipol-dipol interactions with protons, a property
currently exploited for non-invasive oxymetry. Here, we
extrapolate this property through hyperbaric oxygen
exposure.
