OXYGEN-18 ENRICHED WATER
With the growing demand for Positron Emission Tomography (PET) scans as
a diagnostic tool for physicians, Oxygen-18 water has become increasingly
important.
PET is an imaging technique which assists in the diagnosis of many diseases in areas such as oncology, neurology and cardiology. PET allows the physician to examine the whole patient at once, by producing pictures of the functions of the human body unobtainable by other imaging techniques. These images show body metabolism and other functions rather than simply the gross anatomy and structures revealed by conventional x-rays, CT or MRI scans.
To produce these scans F18FDG is needed. To do this, Oxygen-18 Water,
95% or 97% is proton bombarded in a cyclotron to produce Fluorine18F
that is then used in the production of F18FDG in an automated
radiochemical synthesis. The F18FDG is then injected into patients
as an intravenous diagnostic radiopharmaceutical. The PET scan is
then performed on the patient.
Oxygen-18 enriched water, 10% is also used in medical research for energy expenditure studies. This research measures the amount of food that is being metabolized by a person and is often used in Cholesterol research. Medical Isotopes, Inc. can also provide Cholesterol as a standard and the deuterated Cholesterol.
