How are gallium scans done?
A gallium scan is a nuclear medicine test.
It can find cancer, infection and inflammation in the body.

How do they do a gallium scan?

During a gallium scan, a healthcare provider injects a small amount of radioactive material into your bloodstream.
Then a special camera takes pictures of the gallium inside your body..
How is gallium-67 produced?
Production of gallium-67 is undertaken by the proton bombardment of an isotopically enriched zinc-68 target at～21 MeV on medium energy (30 MeV) cyclotrons, via the 68Zn (p, 2n) 67Ga nuclear reaction..
What are the methods of gallium localization?
At least three mechanisms by which Ga-67 may localize in in fections have been postulated.
These include leukocyte labeling (29), lactoferrin binding at the site of infection (30), and direct bacterial uptake (31)..
What are the side effects of a gallium scan?
Side Effects
Chest tightness.cough.difficulty with swallowing.fast heartbeat.hives, itching, or skin rash.large, hive-like swelling on face, eyelids, lips, tongue, throat, hands, legs, feet, or sex organs.trouble breathing.unusual tiredness or weakness..What does a gallium scan detect?
A gallium scan is a test to look for swelling (inflammation), infection, or cancer in the body.
It uses a radioactive material called gallium and is a type of nuclear medicine exam.
A related test is a gallium scan of the lung..
What does gallium bind to?
Gallium (III) (Ga3+) binds to transferrin, leukocyte lactoferrin, bacterial siderophores, inflammatory proteins, and cell-membranes in neutrophils, both living and dead.
Lactoferrin is contained within leukocytes..
What is a gallium scan used for?
A gallium scan identifies the cells that are dividing most quickly in your body.
It can help detect some cancer cells.
It can also help show cells that are rapidly reproducing or responding to an infection somewhere in your body.
People with lymphoma (cancer of the lymph system) may need gallium scans..
What is PET or gallium scan?
What is a Gallium PET/CT Scan? PET-CT (Positron Emission Tomography with Computerised Tomography) is a scanning method that allows us to detect abnormalities in the body.
For this scan we will give you an injection containing a small amount of radioactivity called Gallium-68-DOTATATE..
What is the purpose of a gallium scan?
A gallium scan identifies the cells that are dividing most quickly in your body.
It can help detect some cancer cells.
It can also help show cells that are rapidly reproducing or responding to an infection somewhere in your body.
People with lymphoma (cancer of the lymph system) may need gallium scans..
Where is 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..
Why is gallium-67 an effective medical tracer?
In infections, the gallium scan has an advantage over indium leukocyte imaging in imaging osteomyelitis (bone infection) of the spine, lung infections and inflammation, and for chronic infections.
In part this is because gallium binds to neutrophil membranes, even after neutrophil death..
Why is gallium-67 used in medicine?
Initially, gallium-67 was unexpectedly found to highlight Hodgkin's lymphoma, although it was intended for osseous cancer.
It was later realized that the isotope could be used for a broader range of malignancies and inflammatory processes..
- Gallium (III) (Ga3+) binds to transferrin, leukocyte lactoferrin, bacterial siderophores, inflammatory proteins, and cell-membranes in neutrophils, both living and dead.
Lactoferrin is contained within leukocytes. - Gallium-67 is a cyclotron-produced radiometal with a physical half-life of 78.3 hrs.
It emits up to 10 gamma photons during decay, but the most abundant ones relevant to imaging have energies and relative abundances (%) of 93 keV (39%), 184 keV (21%) and 300 keV (17%). - There are no contraindications to the gallium scan, but precautions should be taken to avoid complications: During pregnancy, whether suspected or confirmed, a clinical decision of risks vs. benefit must be made.
- What is a Gallium PET/CT Scan? PET-CT (Positron Emission Tomography with Computerised Tomography) is a scanning method that allows us to detect abnormalities in the body.
For this scan we will give you an injection containing a small amount of radioactivity called Gallium-68-DOTATATE. - When you receive the actual gallium scan, you will lie on your back on a scanner table for about an hour.
A special camera can then detect where the gallium has built up in your body.
It can then form an image to show where the cells of your body are reproducing the most.
