Abstract: Objective To table a proposal for select using the medical imaging methods to evaluate pelvic injury in forensic field, by studying the structure of pelvis and radiological methods in common use. Methods A study of several cases of pelvic injury was done, in which biomechanics and classification of pelvic injury were analyzed, moreover imaging methods were compared with each other, such as fluoroscopy, X-ray photography, computerized tomography (CT) and so on. Results Four cases of pelvic injury are all multiple injuries, confirmed by X-ray photography and CT examination approvingly. Conclusions Authors advocate that pelvic injury mechanism and biomechanics should be considered accordingly, multiple injuries should be attracted notice, so as to select suitable imaging methods to evaluate pelvic injury exactly.
