Summary

Peripheral artery disease is a worldwide problem, leading to high mortality and mobility.

Critical limb ischemia (CLI) is associated with high risk of amputation with the subsequent decreased in life quality. Endovascular therapy is now considered the primary treatment option in these patients to improve the vascularity and prevent amputations.

In recent years, development of molecular imaging tools are now become available. A recent radio tracer named 18F-Fluoroazomycin Arabinoside (FAZA) its an specific marker of hypoxia in the tissues and has been used in multiples studies. This tracer can be used in PET/MR scan providing a potentially power diagnostic tool in patients with CLI, allowing in one diagnostic study the evaluation of location and degree of hypoxia in the extremity tissues. This diagnostic tool may offer a better assessment pre and post standard of care endovascular treatment for the patients.

Moreover, some of the patients treated with endovascular therapy may not have a favorable outcome, without a clear reason explaining this situation. We will try to find some predictor model in the FAZA PET/MR that can explain the different outcomes and may help clinicians choose the best treatment option in specific cases.

Thirdly, post processing for optimization of the MR sequences in patients with CLI will be performed at the MR component of the PET. There would thus be great clinical interest in developing non-invasive tools that could provide more accurate diagnostic information compared to traditional tests for these patients population.
