A Full Body PET-CT Scan combines Positron Emission Tomography (PET) and Computed Tomography (CT) to provide detailed images of internal structures and functions. Vital Radiology offers this advanced imaging technique to detect cancer, heart disease, and neurological disorders by highlighting areas of high metabolic activity. The scan involves injecting a radioactive tracer, followed by a waiting period, and then capturing images of the tracer. In India, costs vary by city and diagnostic center, ranging from ₹7,000 to ₹40,000. This scan is a valuable diagnostic tool, offering insights into organ function and anatomy to guide treatment planning and disease management.
What is PET/CT Scanning?
PET/CT scanning combines two powerful technologies: Positron Emission Tomography (PET) and Computed Tomography (CT). PET scanners use radiopharmaceuticals, such as the FDG tracer, to detect metabolic activity in the body, highlighting areas of high activity. CT imaging provides detailed pictures of internal structures. Together, PET/CT creates a complete picture of both function and anatomy. This hybrid scan helps doctors diagnose and track diseases like cancer, neurological disorders, and heart conditions.
By merging functional and anatomical data, PET/CT enhances diagnostic accuracy and supports personalized treatment plans, giving patients the best possible care and outcomes in a single, efficient scan.
Why is a Full Body PET-CT Scan Done?
Here are the major reasons why a doctor may recommend a full-body PET/CT scan:
Cancer Detection & Staging
- Early Cancer Diagnosis: Detect cancer at its earliest stage, when it’s most treatable.
- Monitoring Tumor Progression: Track changes in tumor size and activity over time.
- Checking for Recurrence: Identify cancer recurrence after treatment, enabling prompt intervention and improving patient outcomes in oncology.
Heart Disease Evaluation
- Identifying Areas with Poor Blood Flow: Pinpoint areas of reduced blood flow to the heart muscle.
- Diagnosing Coronary Artery Disease: Accurately diagnose coronary artery disease using cardiac PET scan, enabling targeted treatment and improved cardiovascular care in cardiology.
Brain Disorder Diagnosis
- Alzheimer’s Disease: MRI and PET scans detect amyloid plaques and tau tangles.
- Epilepsy: Advanced imaging techniques pinpoint seizure origins.
- Dementia: Brain scans reveal underlying causes (vascular, frontotemporal).
- Brain Tumors: MRI and CT scans identify tumor location, size, and type.
What Are the Risks and Side Effects of a PET/CT Scan?
Is a PET/CT scan safe? When considering a PET/CT scan, understanding the potential risks is crucial for radiology safety.
- Radiation Exposure: Minimal radiation exposure from both PET and CT scans.
- Allergic Reactions: Contrast dye allergy may cause reactions, such as hives or itching.
- Pregnancy Precautions: Not recommended for pregnant women due to radiation risks to the fetus.
- Fasting Requirements: Patients may need to fast for several hours before the test to ensure accurate results.
It’s essential to discuss these risks with your doctor and follow their instructions carefully to minimize any potential side effects.
What to Expect During a PET-CT Scan Procedure?
PET/CT scan procedure steps have been discussed below:
- Preparation: A nuclear medicine technician will explain the procedure and prep you for the scan.
- Injection: A radiologist injects a small amount of radioactive tracer.
- Waiting: You wait for 30-60 minutes for the tracer to absorb.
- Scanning: In the scan room, you’ll lie on a table that slides into the PET-CT scanner for 15-60 minutes.
- Duration: The entire process typically takes 2-3 hours. Tips: Wear loose clothing, arrive early, and drink water after the scan to flush out the tracer.
