RT Journal Article SR Electronic T1 Comparison of Pretinning Methods to Label Leukocytes with Technetium-99m JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 64 OP 66 VO 16 IS 2 A1 Gerson, Bonny A1 Ballinger, James R. A1 Reid, Robert H. A1 Gulenchyn, Karen Y. YR 1988 UL http://tech.snmjournals.org/content/16/2/64.abstract AB Leukocytes labeled with technetium-99m using pretinning with stannous complexes of pyrophosphate, glucoheptonate, and gentisic acid were compared with respect to labeling efficiency, time required for labeling, in vitro cell viability, initial lung transit, and image quality following reinjection into normal volunteers. Gentisic acid pretinning was the best method, offering the shortest preparation time, moderate labeling efficiency, rapid lung clearance, and greatest in vivo stability.
