Non-contrast magnetic resonance imaging (NC-MRA) have attracted rising interest in peripheral artery imaging with the benefit of avoiding the risk of contrast induced nephropathy. However, it remains challenging to image the diseased peripheral arteries with NC-MRA especially in diabetic patients whose local and/or systemic disease load intrinsic to the diabetes may substantially complicated the overall vessel visibility. Exploration the effect of intrinsic disease load on the image quality of NC-MRA would help optimize candidate selection and disease management of diabetes in the clinical practice.
