  rdf:value "Una técnica de imagen que utiliza compuestos marcados con corta duración emisores de positrones radionucleidos (como el carbono-11, el nitrógeno-13, oxígeno-15 y el flúor-18) con el objetivo de medir el metabolismo celular. Es útil en el estudio de tejidos blandos, como el cáncer, sistema cardiovascular y cerebral."@es, "An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as cancer; cardiovascular system; and brain."@en ;
