Bone - Foot with Flow

A bone scan can look at the blood supply to the patient’s bones and, unlike an X-ray, examines the metabolism of bones, which may indicate disease.

  • No preparation for the scan is required.
  • The patient will be given an injection of a radioactive tracer (99mTechnetium MDP), which goes to your skeleton. Some images may be taken straight after the injection, particularly if you should query an infection, inflammation or fracture. 
  • The patient will be asked to return to Nuclear Med 2-5 hours later, depending on the area of interest (the smaller the bone structures are the longer the waiting period). This wait enables the tracer to be adequately taken up by the skeleton. The patient may leave the department in this time and there are no restrictions on what they can do (eg. eat, drink), the patient will be encouraged to drink plenty of fluids and void their bladder before the scan. 
  • When the patient returns, images will be taken using a gamma camera and these images plus a written report will be sent to the referring doctor.

How to book

Patients will need to be referred to Nuclear Med by a referring doctor. Patients must select the specific scan/study required by their referring doctor and book an appointment at the most convenient location.


  • Medical aid authorisation (referring doctor to provide patient with specific ICD 10 code for medical aid authorisation)
  • Referring doctor’s name and practice number
