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.
What is Indium-111 used for in medicine?
Indium In 111 oxyquinoline labeled leukocytes may be used as an adjunct in the detection of inflammatory processes to which leukocytes migrate, such as those associated with abscesses or other infection, following reinjection and detection by appropriate imaging procedures.
How much does an Indium scan cost?
On MDsave, the cost of an Indium-111 WBC Scan ranges from $946 to $2,849. Those on high deductible health plans or without insurance can save when they buy their procedure upfront through MDsave.
How long does an Indium scan take?
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.
How does an indium scan work?
The indium white blood cell scan, is a nuclear medicine procedure in which white blood cells (mostly neutrophils) are removed from the patient, tagged with the radioisotope Indium-111, and then injected intravenously into the patient. The tagged leukocytes subsequently localize to areas of relatively new infection.
Why is a white blood cell scan done?
A labeled WBC scan is used for detection of abscesses and infection in soft tissues, skeleton, or fever of unknown origin.
What type of radiation does Indium 111 emit?
gamma ray
Indium In 111 oxyquinoline is indicated for radiolabeling autologous leukocytes. Indium-111 decays by isomeric transition and electron capture to cadmium-111, emitting a gamma ray that can be detected with a gamma ray camera.
How is indium 111 excreted?
Elimination from the body of injected indium In 111 oxyquinoline is probably mainly through decay to stable cadmium since only a negligible amount (less than 1%) of the dose is excreted in feces and urine in 24 hours.
What is an indium?
How is an indium scan done?
What is a nuclear test for infection?
A White Blood Cell Scan is a nuclear imaging test that looks for infection, inflammation or an abscess in the body, particularly in the abdomen. The material that allows us to do this scan contains a very small amount of radioactivity, making it safer for the patient.
When to use a 111 indium WBC scan?
The indium 111- tagged white blood cell (WBC) scan is used to help identify regions of inflammation and thus infections when other imaging studies are equivocal or contraindicated. In addition to a 111-indium WBC scan, the gallium 67 radiolabeled scan has been used previously as a type of nuclear imaging scan.
Are there any false positives on 111 indium?
These include an accessory spleen, acute bleed/hematomas, neoplasms, foreign body inflammatory response, and inflammatory bowel disease.[3] Noninfectious etiologies of increased uptake on 111-indium nuclear scans include rheumatoid and gouty arthritis, which may also lead to false-positive interpretations.[3]
Which is better, a gallium scan or an indium scan?
Osteomyelitis not involving the spine (radionucleotide scans utilizing gallium have been shown to be superior to indium alone in detecting osteomyelitis of the spine). [4] Prosthetic joint infection Vascular grafts
