What does an indium scan show?
An indium-111 WBC scan is used to look for a suspected infection. The scan involves the injection of radioactive white blood cells into the vein through a small needle, followed by a gamma camera scan to confirm or exclude a clinically suspected infection.
How is an indium scan done?
A small amount of blood will be drawn from a vein in your arm. The technologist will then work with your blood sample to make the blood sample radioactive with a material called Indium. This process takes approximately 2-3 hours at which time you may leave the area if you choose. You will be given a time to return.
What is tagged WBC scan?
A Nuclear Medicine WBC Scan is performed using a special radioactive material which is tagged to your white blood cells that, when injected into the body, is attached to sites of inflammation. Once distributed in these areas, the inflammation (infection) can be seen.
What is the half life of indium-111?
2.8 days
Indium In 111 decays by electron capture with a physical half-life of 67.2 hours (2.8 days). The energies of the photons that are useful for detection and imaging studies are listed in Table 1.
What is a nuclear test for infection?
A gallium scan is a type of nuclear scan that can find cancer, infection or inflammation in the body. A radiologist injects a small amount of a radioactive substance into the bloodstream. The gallium settles in areas of the body where there is inflammation or infection.
How is indium 111 used?
In can be used as a label for red cells, platelets, and leukocytes. It is prepared in a cyclotron by proton bombardment of a cadmium target. It has two major gamma-photon emissions—173 keV (90.5% yield) and 247 keV (94% yield)—which are excellent for counting in a gamma counter and for external imaging.
