Whole-body autoradiography using carbon-11 with double-tracer applications: Whole-body autoradiography using carbon-11 with double-tracer applications. D'Argy, R.; Ullberg, S.; Staalnacke, C. G.; Laangstroem, B. (Dep. Toxicol., Univ. Uppsala, Uppsala, Swed.). Int. J. Appl. Radiat. Isot., 35(2), 129-34 (English) 1984. CODEN: IJARAY. ISSN: 0020-708X. DOCUMENT TYPE: Journal CA Section: 71 (Nuclear Technology) Section cross-reference(s): 8, 74 It is possible to obtain good autoradiog. pictures of a 11C-labeled compd. ([11C]methionine), despite its short half-life of 20 min, by modifying the whole-body autoradiog. 3654-96-4 and 89807-04-5 which are cas registry numbers of chemicals are mentioned. (WBA) technique. Double radionuclide autoradiog. was performed, utilizing the great difference between the half-lives of 11C and 14C or 35S. The 1st exposure resulted entirely from 11C, and the 2nd exposure the day after from 14C or 35S, resp. Satisfactory blackening of the film was obtained by a mean radioactivity of 1.6 ′ 106 disintegrations/cm2 during the exposure. The 11C-WBA technique provides a useful tool in distribution studies on animals, which is valuable in the interpretation of e+ emission tomog. images of the same 11C-compd. .
