Cold agglutinin disease, or cold antibody autoimmune hemolytic anemia, is a rare form of autoimmune hemolytic anemia in which the body’s immune system attacks and destroys its own RBCs. This case addresses an altered biodistribution pattern of radiolabeled RBCs in the presence of suspected cold agglutinin disease observed during a multigated acquisition. %U https://tech.snmjournals.org/content/jnmt/47/2/175.full.pdf
