Cancer cells require a great deal of sugar, or glucose, to have enough energy to grow. PET scanning utilizes a radioactive molecule that is similar to glucose, called fluorodeoxyglucose FDG. FDG accumulates within malignant cells because of their high rate of glucose metabolism. Once injected with this agent, the patient is imaged on the whole body PET scanner to reveal cancer growths which may have been overlooked or difficult to characterize by conventional CT, X-Ray, or MRI.
By monitoring glucose metabolism, PET provides very sensitive information regardless of whether a growth within the body is cancerous or not. CT meanwhile provides detailed information about the location, size, and shape of various lesions but cannot differentiate cancerous lesions from normal structures with the same accuracy as PET. Separate full reports are generated from each division for each patient.
