In diagnosing pulmonary embolism, radioisotope scanning has dominated during regular working hours and computed tomography during on-call hours.
A cyclotron is required to produce fluorine18, a radioisotope with a half-life of less than 2 hours (110 min), which makes storage impossible.
Consider laboratory-based alternatives to in situ experiments involving any radioisotope, stable isotope, or other tracer.
These variables were measured before the animal was placed on bypass and then at the same five points as the radioisotope injections.
Laser generation of proton beams for the production of short-lived positron emitting radioisotopes.
A reactor or radioisotope source generates heat.
Model equations for condensation biosynthesis using stable isotopes and radioisotopes.
Carotid blood flow was measured continuously by the electromagnetic flow meter placed on the single common carotid trunk and cerebral blood flow was measured by radioisotope microspheres.
