Gamma Camera

A gamma camera, also known as a scintillation camera, is a specialized medical imaging device used to capture images of the internal structures of the body. It is primarily used in nuclear medicine, a branch of medical imaging that involves the use of radioactive materials to diagnose and treat various medical conditions.

Gamma cameras are non-invasive and can provide valuable information for physicians to diagnose and monitor various medical conditions. They are an essential tool in nuclear medicine and contribute to the field's ability to offer personalized diagnostic and treatment plans based on a patient's specific medical needs.

Common gamma camera studies

  • Bone scan: to look for spread of cancer to bones, hidden fractures or infection
  • Thyroid scan: to assess an overactive thyroid or nodules
  • Kidney scans (such as DTPA or DMSA): to measure how well each kidney works and check for drainage problems or scarring
  • Other studies of the heart, lungs, liver, gallbladder and glands, as advised by your doctor

Please check with our team which studies are available and how to book.

How it works

A very small amount of a radioactive tracer is given, usually by injection and sometimes by mouth. The tracer collects in the organ being studied, and the gamma camera picks up the signal to create images that show how the organ is working, not just how it looks.

Preparing for the scan

  • Preparation depends on the test; you will be told whether you need to fast or stop any medicines
  • Thyroid scans may need certain thyroid medicines to be stopped beforehand, but only on your doctor's advice
  • Bring previous reports and scans
  • Tell the team if you are pregnant, may be pregnant or are breastfeeding

On the day

Some scans are done soon after the tracer is given; others, such as bone scans, need a waiting period of a few hours. You will lie still on the scanner bed while the camera moves close to your body. Drink plenty of water after the scan unless told otherwise.
