When doctors need a clearer picture of what is happening inside the body, a PET CT scan can provide valuable information that routine imaging may not show. For patients searching for PET CT scan in Delhi, understanding how the test works, when it is recommended, and how to prepare can make the entire process less stressful.PET-CT combines two different imaging techniques—Positron Emission Tomography (PET) and Computed Tomography (CT). While the CT component shows the body’s structure, the PET component highlights areas of increased metabolic activity. When these images are combined, doctors can get a more detailed view of both the structure and function of tissues.PET-CT is particularly important in cancer care, but it can also be used for selected neurological and cardiac conditions.
