Bone scan preparation
Informed by recognized medical guidance
Overview
A bone scan is a special type of scan that uses a small amount of radioactive material (called a tracer) to look at your bones. It helps doctors check for problems such as infections, fractures, or cancer that has spread to the bones. The tracer highlights areas where bone is growing or repairing itself.
Key facts
- A bone scan is safe and the radiation dose is low – similar to a few X-rays.
- You will have a small injection of the tracer into a vein, then wait a few hours before the scan.
- The scan itself is painless and takes about 30 to 60 minutes.
- You can usually eat and drink normally before the appointment, but follow any specific instructions from your hospital.
