RT Journal Article SR Electronic T1 Developing Radiopharmaceuticals JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 65 OP 71 VO 12 IS 2 A1 Plankey, Michael W. A1 Lind, Sharon A1 English, Robert J. A1 Holman, B. Leonard YR 1984 UL http://tech.snmjournals.org/content/12/2/65.abstract AB This is the second of a series of continuing education articles on radiopharmaceuticals. After reading and studying this article, the nuclear medicine technologist will be able to: (1) identify the clinical utility of each new radiopharmaceutical described; and (2) discuss technical considerations, such as amount of activity administered, imaging times, radiation dosage, and pitfalls of each. New radiotracers will play an important role in the future of nuclear medicine. This article discusses the technical aspects and potential clinical efficacy of three new radiotracers: gold-195m, iodine-123 amphetamines, and technetium-99m DTPA aerosols.
