FDG Imaging for Oncology and Neurology

What is FDG PET/CT Imaging?

FDG PET/CT is one of the most widely used imaging techniques in oncology and neurology. It uses a small amount of radioactive glucose (fluorodeoxyglucose, or FDG) to highlight areas of increased metabolic activity in the body. Cancer cells and diseased tissue often use more glucose than normal tissue, allowing FDG PET/CT to reveal tumors, metastases, or abnormal brain activity with high accuracy.

Clinical Advantages of FDG PET/CT Imaging:

  • Detects cancer earlier than many conventional imaging techniques

  • Provides whole-body imaging to assess both primary tumors and metastases

  • Offers valuable information for staging cancer, guiding treatment, and evaluating response

  • Identifies areas of abnormal brain activity related to neurological conditions such as epilepsy, dementia, or neurodegenerative diseases

  • Non-invasive, quick, and well tolerated

Appropriate Candidates for FDG PET/CT

FDG PET/CT may be recommended for patients with:

  • Newly diagnosed cancers (to stage disease and guide treatment)

  • Known cancers (to assess spread or monitor response to therapy)

  • Neurological conditions such as unexplained seizures, memory loss, or suspected Alzheimer’s disease

  • Recurrent or persistent symptoms that need further evaluation

What To Expect

  • Pre-Scan Preparation: You may be asked to fast for 4–6 hours before the scan to ensure accurate results. Drink plenty of water.

  • Tracer Injection: A small amount of FDG is injected into a vein in your arm. This tracer is safe, has no side effects, and leaves the body quickly.

  • Uptake Period: You will rest comfortably for about 45–60 minutes while the tracer circulates.

  • Scan: The PET/CT scan itself takes 20–30 minutes. The scanner is open on both ends for comfort.

  • Results: Your physician will receive results within 24–48 hours.

The Power Of Knowing

FDG PET/CT is a powerful diagnostic tool that not only helps detect cancer but also provides crucial information about how your body’s tissues are functioning. This allows doctors to create more personalized treatment plans and improve long-term outcomes.
