All of the following scintigraphic methods are often used in the diagnosis of fever of unknown origin (FUO) EXCEPT
2.
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:
3.
Human antimurine antibody (HAMA) is being produced when:
4.
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:
5.
Radiopharmaceuticals used in imaging of infection and inflammation accumulate in the region of interest because of the locally changed physiologic conditions. An infectious/inflammatory process is characterized by all of the following EXCEPT:
6.
Which of the following diagnostic test uses radioactive material to visualize the drainage of fluid by the lymphatic system?
7.
To lessen the ability for the development of human anti-mouse antibodies (HAMA), it is possible to retain the immunospecific portion of the antibody that has been encoded as a murine protein, while replacing a large portion of the remainder of the mouse immunoglobulin g (IgG) molecule with:
8.
Images obtained shortly after injection of leukocytes labeled with In-111 or Tc-99m are characterized by intense pulmonary activity that clears and approaches background level by:
9.
In-111 and Tc-99m-labeled white blood cells (WBC) accumulation have been observed in all of the following conditions/sites EXCEPT:
10.
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:
