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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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.

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" ...

“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 ...

Imagine being able to watch organs and tissues work in real time. That's the power of Positron Emission Tomography (PET) imaging, a technology that gives physicians and researchers a window into ...

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 ...
