Xenon-133 (brand name Xeneisol, ATC code V09EX03) is an isotope of xenon. It is a radionuclide that was inhaled to assess pulmonary function, and to image the lungs, but is now discontinued. It was also used to image blood flow, particularly in the brain. 133Xe is also an important fission product.
