General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
Fibrous dysplasia can affect one bone or several. In a prescribed assessment, a bone scan helps the team map skeletal lesions, including those beyond a bone already known to be affected.
A mildly radioactive tracer is injected into a vein, then a camera records its uptake in the skeleton. The nuclear medicine team explains the steps and the total time to allow.
After the injection, a waiting period allows the tracer to be taken up: for bones this can take several hours. You need to stay still during imaging. Ask the team for its instructions about drinking and using the toilet.
Tell the team before the examination if you may be pregnant or are breastfeeding. The team will assess the precautions appropriate to your situation. Also report your medicines and do not change them on your own.
Bring the referral, your medicine prescriptions and relevant previous results, especially bone images and reports. Ask whether special preparation is needed: instructions differ by type of scan.
In fibrous dysplasia, scintigraphy complements other examinations and does not replace their interpretation. Ask how to receive the images and report, then ask your doctor what their distribution means for your assessment.
