PET is a way of imaging how the body is functioning; this is different to CT and MRI, which are used to visualize the structure of the body. In some cases, PET can identify abnormal activity before it is visible on CT or MRI. When used in conjunction with CT and MRI, PET can provide an even more valuable picture of the body.
