It’s crucial to follow these instructions carefully to ensure accurate results and avoid the need for repeat testing.
What is a bone scan, and how does it work?
A bone scan is a diagnostic imaging test used to visualize the bones and detect various bone disorders, such as bone cancer, osteoporosis, or bone infections. The test involves injecting a small amount of radioactive tracer into a vein, which accumulates in the bones and emits gamma rays. These rays are then detected by a special camera, which creates images of the bones.
The radioactive tracer used in bone scans is usually technetium-99m, which has a short half-life and is excreted from the body quickly. The scan itself is painless and typically takes around 30-60 minutes to complete. The images obtained from the scan can help doctors diagnose and monitor various bone conditions, as well as track the effectiveness of treatment.
How long before a bone scan should I stop drinking coffee?
