15o h2o - 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.
