One of the promising, noninvasive and contactless methods for visualizing the vascular system is laser speckle contrast imaging. This study studies the possibility of using magnetic resonance contrast agents in laser speckle contrast imaging and optical coherence tomography, for the first time, on rat ears, under conditions of alloxan\u2010induced type 1 diabetes. By combining diagnostic techniques, the study investigated the ability to differentiate between healthy rat tissue and diabetic rat tissue based on dynamic and structural changes caused by local application of magnetic resonance agents.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study explores the possibility of using magnetic resonance contrast agents for laser speckle\u2010contrast imaging and optical coherence tomography of rat ears under conditions where alloxan\u2010induced type 1 diabetes mellitus is developing was studied for the first time.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Kinetics of scattering coefficient (\u00b5<jats:sub>s<\/jats:sub>) for healthy and diabetic rats during optical clearing were evaluated.
