How Gallium 67 Made?

Gallium-67 citrate is produced by a cyclotron. Charged particle bombardment of enriched Zn-68 is used to produce gallium-67. The gallium-67 is then complexed with citric acid to form gallium citrate. The half life of gallium-67 is 78 hours.

Where is gallium-67 found?

After intravenous administration of Ga-67, the complex dissociates to become bound to transferrin. The principal organs that localize gallium are the liver, spleen, and bone marrow.

What type of emitter is gallium-67?

Gallium-67

Ga is a gamma (93, 184, 296, and 388 keV) emitter, used in SPECT imaging. It is produced with cyclotrons, and it has half-life of 78.3 hours (3.3 days). Ga-citrate and -chloride were extensively used for imaging inflammation and infections of musculoskeletal origin in the 1970s and early 1980s.
