A PET/CT scan combines PET and CT into one image to evaluate the biological and metabolic activity of tumors, the heart, and the brain. PET utilizes a low-level radiopharmaceutical to visualize processes within the body. Malignant or cancerous tumors are metabolically active & grow more rapidly than normal cells, therefore will require more glucose for energy. Consequently, PET is very good at determining whether or not a tumor is malignant through its metabolic activity.
