Before and after the surgery, a procedure called lymphoscintigraphy will be performed. Lymphoscintigraphy is a special type of imaging where a dye, called a radiotracer, is injected and then detected by a special camera. The pictures provided by the lymphoscintigraphy allow investigators to look at the lymphatic system, which is a small network similar to blood vessels that helps drain extra fluid. The lymphoscintigraphy will help investigators to know what method of performing the tummy tuck leaves the lymphatic system most intact.
