Bone Scan
A bone scan may be done on an outpatient basis or as part of your stay in a hospital. Procedures may vary depending on your condition and your healthcare provider’s practices.
You will be asked to remove any clothing, jewelry, or other objects that may get in the way of the scan. A bracelet with your name and an identification number may be put on your wrist. You may get a second bracelet if you have allergies.
If you are asked to remove your clothing, you will be given a gown to wear.
An IV (intravenous) line will be started in your hand or arm for injection of the radioactive tracer.
The tracer will be injected into your vein. The tracer will be allowed to collect in the bone tissue for a period of 1 to 3 hours. You may be allowed to walk around or even leave the facility during this time. You will not be hazardous to other people, as the tracer gives off less radiation than a standard X-ray.
During the waiting period, you will need to drink 4 to 6 glasses of water to help flush out any tracer that does not collect in the bone tissue.
If your bone scan is being done to look for bone infection, a set of scans may be done right after the injection of the tracer. Another set of scans will be done after the tracer has been allowed to collect in the bone tissue.
When the tracer has been allowed to collect in the bone tissue for the right amount of time, you will be asked to empty your bladder. This is because a full bladder can distort the bones of the pelvis and may become uncomfortable during the scan.
You will be asked to lie still on a padded scanning table. Any movement may affect the quality of the scan.
The scanner will move slowly over and around you several times as it detects the gamma rays given off by the tracer in the bone tissue.
You may be repositioned during the scan to get certain views of the bones.
When the scan has been completed, the IV line will be removed. It takes about 1 hour to do a full body scan.
While the bone scan itself causes no pain, having to lie still for the length of the procedure might be uncomfortable, particularly if you have recently had surgery or an injury. The technologist will use all possible comfort measures and complete the procedure as quickly as possible to reduce any discomfort or pain.
