Nuclear medicine

Nuclear medicine scans use radioactive tracers to show the structure and functions of the organs in the body.

A gamma camera and computer are used to produce the scans. These are then processed and images prepared, from which the radiologist prepares a report for your doctor.

Before and after

Before

  • You should drink plenty of fluids before your scan
  • This helps to flush the radioactive tracer through the system more quickly
  • You should go to the toilet often
  • You do not need to have a full bladder

After

You will be asked to avoid close contact with children and pregnant ladies for a period of 24 hours after the scan.

Cardiac ventriculogram (Ejection fraction)

This examination uses radioactive tracers to show the movement of the heart and to assess its function.

This information is useful for doctors to plan the correct treatment for you.

When you arrive in the Nuclear Medicine Department, the radiographer will give you an injection. This is not radioactive. There will then be a wait of 30 minutes, before a second injection is given, which is the radioactive tracer.

Before starting the scan we will attach ECG leads to your chest. It would be useful if you could wear loose fitting clothing.

The scan lasts for about 15 minutes, after which you will be free to leave the department.

Results

Your consultant will make arrangements with you to discuss the results of the scan.
