NCIt definition : An inert, radiopharmaceutical of oxygen-15 (O-15) labeled water used as a tracer molecule
with positron emission tomography (PET). Upon administration, water O-15 is freely
diffusible and its distribution, as well as its clearance, are completely dependent
on the rate of blood flow. Water O-15 can be imaged using PET to measure tissue or
tumor blood flow/perfusion. This cyclotron product has a very short half life of about
2 minutes thereby allowing for multiple, serial measurements.;
