Infection & Tumor Imaging
WBC Ceretec or Indium WBC Scan
Your physician has recommended that you have a Ceretec or Indium-111 white blood cell scan, also called Ceretec or Indium WBC-tagged Scan. This procedure is used to check your body for the presence of infection. Sixty milliliters of blood will be drawn from your arm vein. This blood will be sent to the nuclear pharmacy to separate your white blood cells (WBC's) from the rest of the blood and then tagged with a radioisotope, either Technitium 99M Ceretec or Indium-111. Your radioactive white blood cells will be re-injected through a vein in your arm. Your whole body or the area of interest will be scanned 2 to 3 hours after injection.
The Radiologist will review the images and a report will be sent to your physician who will contact you and discuss the results with you.
The following are reasons your doctor may order a Gallium scan.
To locate areas of tumor involvement, such as lymphoma
Detect abscess or infections in bones
Fever of unknown origin (FUO)
Monitor response to antibiotic treatment
Diagnose inflammatory conditions ex: pulmonary fibrosis or sarcoidosis
Assess for metastasis in patients with known primary cancer
Assess effectiveness of cancer treatment
Your doctor has ordered a gallium scan. This is a safe and effective diagnostic radioisotope that gives off a small amount of radiation. Gallium scan helps locate specific sites of tumor, abscess, inflammation or other abnormalities within the body.
There is no special preparation before you receive the Gallium injection. You may eat and drink as normal
Recommended Imaging Schedule:
For abdominal abscess: 2-6 hours post injection
For tumor: 24, 48 and as recommended by radiologist
Bowel preparation may be needed for follow-up imaging. The most commonly recommended prep is 1-2 tsp Milk of Magnesia in the evening before the 24, 48, and 72 hour recommended images. Let your physician know if you are allergic to milk of magnesia or any of it's ingredients. Your physician will then recommend an alternative if necessary.
• Imaging is typically done starting at 24 hours post injection, then 48, 72 and 96 hours as needed
• Each imaging session will require 60-90 minutes
Do not breastfeed two weeks before a Ga67 scan, to avoid accumulation of Gallium in the breast tissue.
It is recommended that you don’t resume breastfeeding for 4 weeks following the scan. Be sure to talk to your doctor about the benefits and risks prior to scheduling your procedure.
No contrast material (ex: Barium) or medication that contains bismuth (ex: Pepto Bismol) 4 days prior. These can interfere with test results.
