Renal medullary hypoperfusion and hypoxia play a pivotal role in acute kidney injury. Invasive but quantitative physiological methods are used for targeted probing of kidney perfusion as well as regional perfusion and oxygenation in animals in vivo. We set out to combine invasive techniques and non-invasive MRI in an integrated hybrid setup with the ultimate goal to monitor and interpret parametric MR and physiological parameters by means of standardized interventions. Our preliminary results demonstrate that simultaneous measurement of tissue pO2, flux, renal blood flow, arterial blood pressure and MRI is feasible.
