PET-CT and Nuclear Medicine

These scans and tests use small amounts of radioactive material to diagnose and treat a variety of diseases. We have extensive tests available including the only Rubidium Cardiac PET scanning currently available in London, which offers significant benefits over comparable scans.

Rubidium cardiac PET-CT Scan

A Rubidium cardiac PET-CT (positron emission tomography & computed tomography) scan allows us to look at the blood supply to your heart using a small amount of a radioactive tracer (Rubidium) which is injected into a vein in your arm.  This allows the doctor to view your heart under stress and rest to assess whether there is any occlusion or shortage of blood supply. The key benefits of using this particular tracer are:

  • Short 1 hour protocol in total (stress + rest)
  • Reduced radiation burden to patients (approximately 1/4 dose of SPECT tracers)
  • Suitable for patients with high BMI (>35)
  • Absolute myocardial flow quantification
  • Imaging at peak of stress
  • Improved diagnostic/prognostic accuracy
  • Ability to perform CTCA in same appointment


A PET FDG scan involves an injection of a very small amount of radioactive tracer similar to sugar called Fluorodeoxyglucose, or FDG for short. This tracer is taken up by parts of your body which use more energy such as infection, inflammation or cancerous tumours. There are no immediate side-effects and the distribution of the tracer helps your doctor to understand and diagnose any health problems you have been experiencing; this will then help them decide on further treatment for you.

Myocardial perfusion SPECT study

SPECT imaging provides a non-invasive way of measuring blood supply to your heart tissue using a radioactive tracer which can display ischemia (shortage of blood supply to the heart) or infarction (death of heart tissue). This information will aid your doctors in deciding the best treatment regimen for you.

We can also undertake a wide number of nuclear medicine tests, please contact our team for further details.
