Buck A, Nguyen N, Burger C, Ziegler S, Frey L, Weigand G, Erhardt W, Senekowitsch-Schmidtke R, Pellikka R, Bläuenstein P, Locher JT, Schwaiger M. Buck A, et al. Eur J Nucl Med. 1996 Dec;23(12):1619-27. doi: 10.1007/BF01249625. Eur J Nucl Med. 1996. PMID: 8929316
There is a need for a quantitative myocardial perfusion agent that does not require an on-site cyclotron. Early studies with manganese demonstrated that this trace metal is of potential use for myocardial imaging. 52mMn can be produced in a 52Fe-52mMn generat …
