798 views
A gamma scan is primarily used in nuclear medicine to diagnose or monitor disease progression. It's helpful in identifying cancerous cells, assessing organ function, and tracking bone density. The scan involves injecting a small amount of radioactive tracer into the body, which emits gamma rays captured by a special camera. This provides detailed images of internal structures and functions, aiding in precise medical assessments.
FAQs & Answers
- What is a gamma scan? A gamma scan is a medical imaging technique that uses radioactive tracers to visualize internal organs and functions.
- How does a gamma scan work? It involves injecting a small amount of radioactive material that emits gamma rays, captured by a specialized camera to create images.
- What conditions can a gamma scan help diagnose? Gamma scans are useful for diagnosing cancer, assessing organ function, and monitoring conditions like bone density.
- Is a gamma scan safe? Yes, gamma scans are generally safe as they use low levels of radioactive materials, but consult your doctor for specific concerns.
