Recent developments allowing direct visualization of
cellular structure in excised mammalian tissue using MRI
techniques have created a need for micro-perfusion
equipment capable of operating in conjunction with
high-field spectrometer hardware. This study details the
design and fabrication of an in-bore oxygenator capable
of offering precise control of perfusate properties
including pH and dissolved gas (O
2
&
CO
2
) content. In addition, a stability
assessment is conducted which compares diffusion signal
reproducibility over time under conditions of constant
perfusion as compared to a static control group.
Findings indicate statistical equivalence at 13 of 14
time-points sampled over a 21 hour period.
