A PET/CT scan examines the body’s chemistry and biological processes. PET/CT scanning utilizes a radioactive molecule that is similar to glucose, called fluorodeoxyglucose (FDG) which is useful in the detection of cancer cells, as they require a great deal of sugar (or glucose) to have enough energy to grow. FDG accumulates within the malignant cells because of their high rate of glucose metabolism. One hour after injection of the FDG tracer, the patient is imaged on the PET/CT scanner to reveal cancer growth that may have been difficult to characterize by conventional CT, MRI or X-ray.
The PET/CT scanner enables the combination of two imaging modalities, which can provide additional diagnostic information to the interpreting physician. By monitoring the glucose metabolism, PET/CT provides very sensitive information about the biologic processes within the patient. The CT portion of the study provides detailed information about the location, size and shape of various FDG metabolic lesions to better differentiate active cancerous lesions from normal structures. PET/CT is more accurate than either PET or CT alone.
