Fluorescence guided surgery is a technique used in medical procedures to enhance visualization of target tissues or structures within the body. This method involves the use of fluorescent dyes or probes that selectively bind to specific target molecules, such as cancer cells or vital organs, and emit light when exposed to a specific wavelength of light. By using specialized imaging devices, surgeons are able to accurately identify and distinguish between diseased and healthy tissues during surgery, thereby improving the precision and outcome of the procedure. Fluorescence guided surgery is commonly used in oncology, neurosurgery, and other surgical specialties to improve the accuracy of tumor resection and ensure complete removal of cancerous cells.
