WBC labeled abdominal scintigraphy scan
in Health ·
Hello,
This is one of those questions where you really need an answer from the professionals actually running the department.
From what I recall—and this is based on some old nuclear medicine lecture notes from quite a while back—the protocol for scintigraphy in inflammatory bowel disease involves drawing blood first. They have to isolate the leukocytes from that sample and label them with a radiopharmaceutical. It’s a process that takes several hours.
Once those white blood cells are labeled, the patient returns to have them injected, followed by the actual scan. My memory serves me that the imaging usually happens about four hours after the injection, though different facilities might follow different protocols.
Your best bet is to call the clinic directly to confirm. You can find here their website with the contact number.
What you read online likely refers to in vivo abdominal scintigraphy using labeled erythrocytes, which is a completely different test. This specific procedure uses leukocytes that are labeled outside the body (in vitro). Consequently, the appointment will probably take longer. You have to account for the time needed to label the cells after the draw, plus the waiting period after the injection before they can scan you. Once you factor in the travel and waiting room time, you should expect to be in Chicago for a good chunk of the day—perhaps seven hours, maybe more, maybe less.
Mind you, it’s been ages since I sat through those lectures, so I can't give you a definitive guarantee. If I've misremembered any details, I apologize. Please check with the clinic first.
Best regards. 🙂
