an imaging technique that examines the biological
origins of disease so that illness may be diagnosed and treated at
an earlier stage and more effectively. PET allows physicians to visualize
the patient's whole body with just one scan. This scan is able to
identify areas with increased activity (such as cancer cells). Conventional
X-rays or CT scans may detect the same areas of activity, but only
after they have become larger and at a later stage.
Whole body PET imaging identifies abnormalities that might otherwise
go undetected and guides physicians to the most appropriate treatment
for the disease to which it is applied. For example, PET can detect
tumors unseen by other imaging techniques or detect Alzheimer's disease
one to two years before the diagnosis would be made clinically.
PET is safe, and replaces multiple medical testing procedures with
a single exam by showing all the systems of the body with one image.
It can effectively pinpoint the source of many of the most common
cancers, heart and neurological diseases, eliminating the need for
redundant tests and diagnostic surgical procedures. PET is
a powerful, proven diagnostic imaging modality that significantly
reduces multiple medical costs and avoids needless pain to the patient.
