What is a Positron Emission Tomography exam?
Positron emission tomography (PET) is a nuclear medicine procedure that produces pictures of the body’s biological functions. PET is a unique diagnostic imaging modality that is capable of detecting certain diseases before other imaging modalities, including computed tomography (CT) and magnetic resonance imaging (MRI). PET is able to capture chemical and physiological changes related to metabolism, as opposed to gross anatomy and structure, which is obtained by CT and MRI. This is important since functional changes are often present before structural changes in tissues. PET images may therefore demonstrate pathological changes long before they would be evident in CT or MRI. PET/CT is valuable because it combines the pathological information with the anatomical giving your doctor a large amount of information to make the most informed decision.
