Obesity has major repercussions on public health. In obese people, increased inflammation and insulin resistance are observed, leading to cerebrovascular problems and increased susceptibility to neurodegenerative diseases. Vascular fragility can also lead to serious complications such as stroke. Assessment of blood flow regulation is therefore crucial in metabolic disorders. Laser speckle contrast imaging (LSCI) is a high-resolution technique widely used in preclinical imaging, particularly in the brain, to map blood flow at the tissue surface in vessels with a diameter of 10 micrometers. Multi-exposure speckle imaging (MESI) improves flow quantification, particularly in the presence of static diffusers (i.e. skin, bone). MESI imaging has a...
