A PET (Positron Emission Tomography) scan is a powerful diagnostic tool used by Sanitas to detect abnormal metabolic activity in the body. It produces detailed 3D images that show how organs and tissues are functioning, rather than just how they look. PET scans are especially useful in diagnosing certain cancers, neurological conditions, and heart problems.
During a PET scan, a small amount of radioactive material called a radiotracer is injected into your bloodstream. This substance mimics glucose, which is absorbed more rapidly by areas of high metabolic activity—like cancerous or inflamed tissue. The PET scanner then captures images of how this tracer is distributed, identifying hotspots that may indicate a medical concern.
PET scans are commonly prescribed by Sanitas-affiliated specialists to:
They are often used alongside CT or MRI scans to create a clearer clinical picture.
Before your scan, you may be asked to avoid eating for several hours and refrain from strenuous exercise for 24 hours. Wear loose clothing, avoid metal items, and notify your doctor if you're claustrophobic or pregnant. You'll receive the radiotracer via injection and then wait around 60 minutes before the scan begins.
You'll lie on a narrow motorised bed that slides into a doughnut-shaped scanner. The machine captures images of your body while you stay very still. The scan itself is painless and usually takes 30 to 60 minutes. After the scan, you can usually go home right away.
You’ll be exposed to a small amount of radiation—comparable to natural background exposure over a couple of years. The radiotracer quickly loses its radioactivity and passes through your system naturally. To speed up this process, drink plenty of fluids after the scan. As a precaution, you may be asked to avoid close contact with pregnant women or young children for several hours.
Depending on your condition, your Sanitas specialist may recommend an alternative imaging scan such as:
PET scans are covered under many Sanitas health plans if prescribed by a Sanitas-authorised specialist and pre-approved. Coverage depends on your specific policy, so it’s best to consult your plan documents or ask your advisor before booking your scan.
Once a Sanitas specialist refers you for a PET scan and coverage is confirmed, Sanitas will typically pay the provider directly. This allows you to focus on your health rather than costs. You can request pre-authorisation through the Mi Sanitas app or by calling customer service.
