PET Scan Centres in India

At the heart of PET imaging lies cellular metabolism mapping. The procedure begins with the administration of a radiotracer, most commonly Fluorodeoxyglucose (FDG)—a glucose analog tagged with the radioactive isotope Fluorine-18 (¹⁸F). Cancer cells, due to their accelerated metabolic rate and high glucose consumption (Warburg effect), absorb significantly more FDG than normal tissues.

Once injected into the bloodstream, the radiotracer circulates throughout the body and selectively accumulates in areas of increased metabolic activity—the hallmark of malignant growths. As the radioactive fluorine decays, it emits positrons, which collide with electrons in surrounding tissues. This annihilation process releases gamma photons in opposite directions, detected by the PET scanner’s ring-shaped detectors. The data collected from these photon pairs are then reconstructed by sophisticated computer algorithms into three-dimensional images, mapping real-time biochemical changes within the body.

While PET visualizes metabolic function, CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) provide detailed anatomical information. When combined, PET-CT and PET-MRI offer both functional and structural insights—allowing oncologists to accurately localize tumors, evaluate their aggressiveness, and detect occult metastases even in early or hidden stages.

This fusion of molecular and anatomical data helps in:

• Early cancer detection and staging
  
• Assessing treatment response and residual disease
  
• Planning radiotherapy with precision targeting
  
• Monitoring recurrence or metastasis progression
