Bone Scan Procedure
During the first part of the bone procedure, the radioactive tracer is injected into a vein, usually in your arm. Depending on the reason for the procedure, there may be some pictures taken during and immediately following the injection. There is a two to three hour waiting period between the injection and the bone scan to allow the radioactive tracer to be absorbed by the bones. It is okay to eat during this waiting period. During the waiting period, you should try to urinate as often as possible to help eliminate the excess tracer from your body.
The imaging portion of the bone scan procedure takes about one hour. Pictures that are taken depend on your specific reason for the bone scan. You will lie on the imaging table with the camera positioned above and below you. The camera will move slowly, imaging the entire length of your body taking 15 minutes and/or you could have spot images taken of a specific area of the body. It is extremely important that you remain as still as possible so that the bone scan results are accurate.
