Optical signature of nerve tissue—Exploratory ex vivo study comparing optical, histological, and molecular characteristics of different adipose and nerve tissues

Background: During several anesthesiological procedures, needles are inserted through the skin of a patient to target nerves. In most cases, the needle traverses several tissues—skin, subcutaneous adipose tissue, muscles, nerves, and blood vessels—to reach the target nerve. A clear identification of the target nerve can improve the success of...
