Needles don't bother me so I don't know why I'm so scared. I think it's just because I've been getting poked a lot lately due to multiple blood tests, etc. and I'm sick of it. It's for my leg (tib-fib area). What will this test include? Where will the injection be? Is the needle enormous or small? Thanks for any help you can provide.

Dumpling, the person I talked to said a needle is required. I have to then wait three hours and come back for the test.

It's a radioactive tracer to look for areas of increased uptake. Areas that have stress fractures, for example, have lots of metabolic uptake. The tracer allows the doc to see where these areas are.
>For a bone scan, a radioactive tracer substance is injected into a vein in the arm. The tracer then travels through the bloodstream and into the bones. A special camera (gamma) takes pictures of the tracer in the bones. This helps show cell activity and function in the bones. Areas that absorb little or no amount of tracer appear as dark or "cold" spots, which may indicate a lack of blood supply to the bone (bone infarction) or the presence of certain types of cancer. Areas of rapid bone growth or repair absorb increased amounts of the tracer and show up as bright or "hot" spots in the pictures. Hot spots may indicate the presence of a tumor, a fracture, or an infection.

I don't know what they do. But try to think they know what they are doing. Have faith in them.
