What Is a PET Scan?

A PET scan is a non-invasive imaging test that uses a small amount of radioactive tracer to highlight areas of activity within the body. The scan captures detailed images of organs and tissues, allowing doctors to assess conditions such as cancer, heart disease, and neurological disorders. Unlike other imaging techniques like CT or MRI scans, PET scans reveal metabolic and biochemical changes at the cellular level, often detecting diseases in their early stages.

During the procedure, the tracer is injected into the body, where it accumulates in areas with high metabolic activity. A specialised scanner then detects these areas, producing clear, detailed images that help healthcare professionals diagnose and monitor conditions effectively.

Benefits of a PET Scan

• Early Disease Detection – Identifies cancer, heart disease, and brain disorders at an early stage.
• Accurate Diagnosis – Provides highly detailed images that help in precise medical evaluations.
• Monitoring Treatment Progress – Helps track the effectiveness of treatments, such as chemotherapy or radiotherapy.
• Non-Invasive Procedure – Requires only a small injection of radioactive tracer, with no need for surgery.
• Personalised Treatment Planning – Aids in tailoring treatments based on individual metabolic activity.

Who Might Need a PET Scan?

A PET scan is recommended for individuals who need advanced imaging for various medical conditions, including:

• Cancer Detection and Monitoring – Identifies tumours, evaluates their spread, and checks treatment response.
• Neurological Disorders – Assists in diagnosing conditions such as Alzheimer’s, Parkinson’s, and epilepsy.
• Heart Disease Assessment – Evaluates blood flow and detects damaged heart muscle after a heart attack.
• Unexplained Symptoms – Helps diagnose underlying health conditions when symptoms remain unclear.

Since PET scans involve exposure to a small amount of radiation, it is essential to consult with a healthcare provider to determine if this diagnostic tool is suitable for your medical needs.

What to Expect During a PET Scan

1. Preparation – You may be advised to avoid eating for a few hours before the scan. Your doctor will provide specific instructions based on your condition.
2. Tracer Injection – A small amount of radioactive tracer is injected into your bloodstream. It takes about 30-60 minutes for the tracer to be absorbed.
3. Scanning Process – You will lie on a scanning bed while the PET scanner moves around you to capture images. The process is painless and takes about 30-45 minutes.
4. Post-Scan – You can resume normal activities after the procedure. Drinking plenty of fluids helps flush the tracer from your body.
5. Results – A specialist will analyse the images and discuss the findings with you during a follow-up consultation.
