  2. What is Gallium Scan? • Type of nuclear medicine that uses radioactive tracers. • Radioactive tracers common use in gallium scan. • Gallium 67 radioisotope. 2

  3. How does Gallium Scan Work? • Intravenous • Laxatives or enemas are going to be taken during this procedure. • Patient is scan with gamma cameras that identifies where the high and low concentrations of gallium are in the body. 3

  4. Intravenous Gallium 4

  5. Gallium Scan 5

  6. Risks of Gallium Scan • Exposure to radiation (gamma rays) • Infection, painful or red in the part where the radioisotope was administer. • Person might develop an allergic reaction to the gallium 67 radioisotope. 6

  7. Usage of Gallium Scan • Detect a source of infection that is caused by an unknown fever. • Abscess or infections in bones. • Monitor the response of antibiotic treatment. • Diagnose inflammatory conditions (pulmonary fibrosis or sarcoidosis). • Detection of lymphomas. • Detection of Hodgkins disease. 7

  8. Radiation Emitted from the Gallium Scan 8

  9. Radiation Attenuation by Lead Shielding 9

  10. Replacement of the Gallium Scan • PET scan • SPECT scan 10

  11. PET Scan • Some of the common isotopes used are below 11
