Do tracers trace?

O NLY A FEW YEARS after the discovery of artificial radioisotopes by the Joliot-Curies in 1934, de Hevesy, Chievitz and Ottesen used tracers in hematology. Even today, there are few areas in clinical medicine where as many radioisotopes are used both for investigative and diagnostic purposes as in hematology. Consequently, the methods of tracer studies are often described in the hematologic jou...

How many PET tracers do we need?

The recognized need for new PET tracers is associated with increases in available PET instrumentation and with unmet clinical challenges in the early diagnosis and staging of diseases. The clinical success of (18)F-FDG PET has resulted in the acceptance of biologic signals as part of disease management. The advantages of PET technology over SPECT will lead to the introduction of new PET tracers...

Do scientists trace hot topics?

Do scientists follow hot topics in their scientific investigations? In this paper, by performing analysis to papers published in the American Physical Society (APS) Physical Review journals, it is found that papers are more likely to be attracted by hot fields, where the hotness of a field is measured by the number of papers belonging to the field. This indicates that scientists generally do fo...
