A bone scan is a test used to detect bone diseases and conditions. The test involves injection of a small amount of radioactive material into a vein, which is then absorbed by the bones.
Bone scans are important because they can help identify problems such as fractures, tumors, infections, and arthritis. They can also be used to monitor how well treatment is working for conditions such as cancer and diabetes.
What to Expect During a Bone Scan of the Foot?
When you arrive for your bone scan, you will be asked to remove any jewelry or metal objects that you are wearing. You will then be given a gown to wear.
The technologist will position you on the scanning table and inject a small amount of radioactive material into a vein in your arm. The injection itself is not painful, but you may feel a brief sting or scratch when the needle is inserted.
Once the injection is complete, you will need to wait approximately 30 minutes for the radioactive material to be absorbed by your bones.
After 30 minutes, you will be asked to lie on your stomach on the scanning table so that your feet can be scanned. The technologist will move the scanner over your feet and take pictures from different angles. A number of pictures will be taken after the injection, and up to 3-5 hours later.
Bone scans can be used to diagnose a variety of problems, including stress fractures and osteomyelitis.
