A PET-CT Scan (Positron Emission Tomography – Computed Tomography) is a powerful, hybrid imaging technique that combines metabolic imaging (PET) with detailed anatomical imaging (CT). This advanced diagnostic tool is widely used in oncology, neurology, and cardiology to detect diseases at an early stage, assess treatment effectiveness, and guide precision therapy.
Key Features:
- Hybrid Imaging Technology
- PET Scan: Captures metabolic activity by detecting radioactive tracers.
- CT Scan: Provides high-resolution structural details of organs and tissues.
- Combines both functional and anatomical data in a single scan for enhanced diagnosis.
- Superior Cancer Detection & Staging
- Identifies tumors, metastases, and recurrences with high sensitivity.
- Helps differentiate between benign and malignant lesions.
- Monitors the effectiveness of chemotherapy, radiation, or immunotherapy.
- Neurological & Cardiac Applications
- Brain Imaging: Detects Alzheimer’s disease, Parkinson’s disease, epilepsy, and brain tumors.
- Cardiac Imaging: Assesses myocardial perfusion, detects coronary artery disease, and evaluates heart tissue viability.
- Minimally Invasive & Highly Accurate
- Uses a small dose of radiotracer (e.g., FDG – Fluorodeoxyglucose) for cellular-level imaging.
- Reduces the need for unnecessary biopsies or exploratory surgeries.
- Provides early disease detection, even before structural changes occur.
- Fast & Efficient Scanning Process
- Quick scan time (typically 30-60 minutes).
- Low radiation exposure compared to separate PET and CT scans.
- Requires minimal patient preparation.
Benefits:
✅ Early Disease Detection – Identifies abnormalities at a cellular level.
✅ High Diagnostic Accuracy – Combines functional and structural imaging.
✅ Non-Invasive & Painless – Requires only a simple injection of a radiotracer.
✅ Optimized Treatment Planning – Helps doctors tailor precise treatment strategies.
Applications:
- Oncology: Cancer detection, staging, and treatment monitoring.
- Neurology: Brain disorders, dementia, and epilepsy evaluation.
- Cardiology: Coronary artery disease and heart function assessment.
- Infection & Inflammation: Detects infections, inflammatory diseases, and autoimmune conditions.
