Preoperative imaging navigation of perforator flaps is helpful for locating perforator vessels and harvesting flaps. It can assist doctors to formulate accurate medical plans, reduce waste of medical resources, avoid surgical trauma caused by medical blindness, reduce the incidence of surgical complications, shorten hospital stay, and make patients get better therapeutic effect. With the development of science and technology, the collision and blending of new technologies and theories has promoted the development of interdisciplinary subjects. The traditional imaging assisted diagnosis cannot meet the current clinical needs. This article introduces the clinical application, advantages and disadvantages of common imaging navigation technology and its common clinical application scope, so as to provide reference for selecting appropriate imaging technology before perforator flap operation.
