What Is a Ceretec WBC Scan and How Does It Work?
A Ceretec WBC scan is a high-tech way to find infections and inflammation in the body. It’s great for spotting where infections or inflammation are happening. This helps doctors give better treatment.
Definition and Purpose of White Blood Cell Scans
A white blood cell scan, like the Ceretec WBC scan, finds infections or inflammation in the body. White blood cells are key to fighting off infections. By using a special tracer, doctors can see where these cells go. This shows where infections or inflammation are.
This scan helps doctors diagnose hard-to-spot conditions.
The Science Behind Technetium-99m HMPAO (Ceretec) Labeling
The Ceretec WBC scan uses Technetium-99m HMPAO to label white blood cells. First, white blood cells are taken from the blood. Then, they’re labeled with Technetium-99m HMPAO. After that, they’re put back into the patient.
These labeled cells go to where there’s infection or inflammation. This makes it easy to see where the problem is through imaging.
Types of Infections and Inflammations Detected
The Ceretec WBC scan can find many infections and inflammation types. These include:
- Osteomyelitis (bone infection)
- Prosthetic joint infections
- Inflammatory bowel disease
- Intra-abdominal infections
By finding the exact spot of these problems, doctors can make better treatment plans. This helps patients get better faster.
Medical Conditions That Benefit From a Ceretec WBC Scan
