The article entirled, “Preparation and evaluation of Lu-177 phytate Complex for Radiosynovectomy” published in, pages 22-27, issue 1, vol. 13 of World Journal of Nuclear Medicine[1] is being retracted. It has been found that the concerned article has several overlapping text-sections from a previously published article from the same group of authors, entitled, “Development of 177Lu-phytate Complex for Radiosynovectomy” in pages 705-709, issue 5, vol. 16 of Iranian Journal of Basic Medical Sciences[2]. Hence the article is being retracted on the grounds of duplicity of content.Prof. John Buscombe,Acting Editor in Chief, WJNM, Department of Nuclear Medicine, Addenbrooke's Hospital, Cambridge, CB2 0QQ, UK
