OBJECTIVE: It was found that the residual 99Tcm-bisphosphonates in skeletons of elderly women increased after 24 h. To this end, a nontraumatic approach was used to investigate the pattern of 99Tcm - methylene diphosphonate (99Tcm - MDP) uptake into the body and local bone in healthy women and their relationship to age. Methods: Eighty - four healthy women (33 premenopausal and 51 postmenopausal) received intravenous injection of 997cm -
