Preparation

Preparation not required.
The radiopharmaceutical is administered and in some cases immediate images are taken. The patient has to wait about 2 to 4 hours for the radioactive material to bind to your bone so that delayed images can be taken. During this time, you may be asked to drink 4 to 6 glasses of water so your body can wash out the tracer(injected material) that does not collect in your bones. Just before the scan begins, you will be asked to empty your bladder to prevent any radioactive urine from blocking the view of your pelvic bones during the scan.
