Tissue perfusion rate determined from the decay of oxygen-15 activity after photon activation in situ

Journal Article · · Science; (United States)
Rates of cerbral perfusion were obtained from measurement of the disappearance (wash-out) of oxygen-15 after in situ tissue activation with 45-million-volt x-rays. In an anesthetized cat, typical values were 90 milliliters per minute per 100 grams of tissue, with 55 percent wash-out. In a specific radiotherapy patient, the value was 65 milliliters per minute per 100 grams of tissue, with 63 percent wash-out of oxygen-15 through incorporation into tissue water.
