Each October, the Nobel Prizes celebrate a handful of groundbreaking scientific achievements. For George de Hevesy, the 1943 Nobel Laureate in chemistry who discovered radioactive tracers, that place ...

During a nuclear stress test, you’ll be injected with a radioactive dye called a tracer. Some of this tracer will remain in your system for a time after the test. A nuclear stress test is a type of ...

Center, an ultra-high-performance brain-dedicated scanner called the NeuroEXPLORER (NX) is redefining what is possible in ...

In an advance for medical imaging, scientists from University of North Carolina Lineberger Comprehensive Cancer Center have discovered a method for creating radioactive tracers to better track ...

A patient checks into the hospital with difficulty breathing. Is inflammation to blame? How can physicians visualize areas of inflammation in the respiratory system in order to choose the best course ...

Researchers have completed a successful clinical trial, managing to detect and image radioactive tracers used in PET and in SPECT scans at the same time, with the hope of enabling doctors to scan ...

THIS note gives a brief account of a radioactive tracer technique for the detection and estimation of the short-lived aliphatic free radicals; it is being used in both dynamic and static experiments.

Coronary plaques are blockages that cause narrowing and hardening of the heart's blood vessels, often causing angina (chest pain). When plaques rupture, they can lead to blood clot formation which ...

RADIOACTIVE TRACERS have been used to study the fuel distribution among individual cylinders in two modern V-8 engines. Individual fuel components (both hydrocarbons and fuel additives) were "tagged" ...

Medical imaging has experienced tremendous growth since the discovery of X-rays: the x-ray-based CT scanner, advances in positron emission tomographic (PET) imaging, the development of single photon ...

“Probably the most useful tool for research since the discovery of the microscope” was described in detail last week by Dr. Joseph G. Hamilton of the University of California. The tool he referred to ...

THE scientific programme of this year's anniversary meeting of the Chemical Society was arranged in collaboration with the Chemistry Division of the Government's Atomic Energy Research Establishment.
