A nuclear medicine scan used to determine whether an infant has gastroesophageal reflux. Radioactively labeled milk is given to the child orally, and its progress through the upper gastrointestinal tract (and in reflux, into the lungs) is monitored. The scan is typically used if an infant has had more than one episode of aspiration pneumonia.…

Gated blood pool imaging
Radioisotopic imaging of the heart, especially of the muscular contraction of its walls and of its ejection fraction. Red blood cells are withdrawn and labeled with an isotope of technetium. A sequence of images is taken immediately after the radiolabeled blood is reinjected into a peripheral vein and allowed to circulate. The images are timed…
