All of the following scintigraphic methods are often used in the diagnosis of fever of unknown origin (FUO) EXCEPT
4.
Images obtained shortly after injection of white blood cells labeled with In-111 or Tc-99m are characterized by intense activity-up to 4 hours, but disappearing prior to 24 hours imaging-pulmonary activity. This phenomenon is caused by the fact that:

An organ that removes old red blood cells, holds a reserve of blood in case of hemorrhagic shock, and synthesizes antibodies in its white pulp is called:
8.
Tc-99m-labeled leukocytes and Tc-99m sulfur colloid accumulate in the reticuloendothelial cells of the bone marrow. The distribution of marrow activity is similar for both radiopharmaceuticals with the exception of an acute or chronic bone infection. Osteomyelitis:
