A PET Scan (Positron Emission Tomography) is an advanced imaging test that helps doctors evaluate the metabolic activity of tissues and cells. A small amount of radioactive tracer is used to identify areas with different levels of activity. PET imaging is widely used in cancer evaluation, including assessing disease spread, treatment planning, and monitoring treatment response. A PET CT Scan combines PET’s functional information with CT’s detailed anatomical images. Preparation may include fasting and following specific instructions provided by the diagnostic centre. If your doctor recommends a PET Scan in Chandigarh, proper preparation and professional interpretation are important for reliable diagnostic information.
