Positron Emission Tomography–Computed Tomography (PET/CT) is a highly advanced imaging technique that combines functional and structural information to detect diseases at an early stage. Explore our resources to understand how PET/CT works and why it’s often used in cancer diagnosis and treatment planning.

Early detection is key in the successful treatment of many cancers. A PET/CT scan provides both functional and anatomical insights, making it one of the most effective tools for detecting cancer, monitoring treatment response, and identifying recurrence. It helps doctors pinpoint abnormal cell activity even before structural changes become visible. Don’t wait for symptoms to progress – early imaging can lead to better outcomes.
PET/CT scan services from our Preferred Doctors you can consider:
When facing a potential cancer diagnosis or planning your treatment, getting a second opinion on your PET/CT scan results can offer clarity and reassurance. It allows you to confirm the accuracy of the findings, explore different treatment paths, or gain deeper insights into your condition. This step is especially valuable when major treatment decisions are involved, such as surgery or chemotherapy.
Seeking a second opinion is a wise and common move—many patients do it, and most doctors welcome it. Their priority is your health, and a second opinion can help ensure that you’re making the most informed, confident choice for your care journey.

PET/CT scans that are considered medically necessary are often eligible for claims under national healthcare savings schemes and private insurance plans, depending on your country’s policies and the specifics of your plan. These scans are typically covered when used for diagnosing or monitoring serious conditions such as cancer. However, PET/CT scans requested purely for screening purposes—without any clinical symptoms or referrals—may not be claimable under most insurance policies. It’s best to consult with your healthcare provider or insurer to confirm your coverage eligibility.

PET/CT scans are most commonly used in the diagnosis, staging, and monitoring of cancer, but they’re also helpful for detecting heart conditions and certain neurological disorders. This advanced imaging method can identify abnormal cell activity that may not yet be visible on other scans, making it especially useful for detecting tumors, evaluating cancer spread, and checking treatment response.
A PET/CT scan is typically recommended if there’s a need to:
It may also be used for heart and brain assessments in specific cases. Your doctor will usually order a PET/CT scan based on clinical findings, test results, or concerns that require deeper investigation.
During a PET/CT scan, a small amount of radioactive tracer is injected into your bloodstream. You’ll wait for about 30–60 minutes while your body absorbs the tracer. Then, you’ll lie on a scanning bed that moves slowly through the PET/CT machine. The procedure takes around 30 minutes to an hour. It’s painless and non-invasive, but it’s important to remain still for accurate results.
After the scan, a radiologist will review the combined images and send a detailed report to your doctor. You can usually return to normal activities immediately unless advised otherwise. Your doctor will discuss the results with you and explain any next steps, which could include further tests, treatment, or a specialist referral.
