Researchers at Northwestern University have developed a new biomaterial, selenomelanin, that can help protect people from radiation. The new substance, chemically synthesized and produced by bacteria, helps protect cells from radiation more...
Nuclear medicine relies on two imaging modalities to assess internal function and diagnose disease. Positron emission tomography (PET) typically uses fluorine-18, a radiotracer that releases positrons, and a special scanner to detect the...
Researchers from the University of North Carolina Lineberger Comprehensive Cancer Center have developed new radioactive tracers to track pharmaceuticals in the body and to image cancer. The findings, reported in journal Science, describe the new...
United Imaging Healthcare, a company out of Shanghai, China, won FDA clearance for its uEXPLORER combined Positron Emission Tomography (PET) and Computed Tomography (CT) scanner. The device can perform whole-body scans using both imaging...
Subtle Medical, a firm headquartered in Menlo Park, California, won both FDA clearance and the European CE Mark of approval to introduce its SubltePET system on both sides of the Atlantic.
The system uses artificial intelligence techniques to...
An amazing new PET/CT scanner has produced its first images of human subjects, giving scientists and clinicians new opportunities to treat cancer and other diseases. The EXPLORER is a high sensitivity total-body positron emission tomography...
Medical radioisotopes are widely used in cancer treatment, but their production has been hampered to the point that obtaining them has become a challenge. The lack of Technetium-99m is probably the most widely known, but there's also a shortage...
A good deal of advanced medical imaging to spot cancer tumors, and help to diagnose coronary artery disease and other conditions, relies on injecting radioisotopes into the body whose location can be tracked. The most common is technetium-99m...
During the development of many drugs, radioactive markers and so-called stable labels, typically deuterium and tritium respectively, are often used to trace the destination of chemical compounds and their metabolites. This is a pretty easy...
Researchers from Memorial Sloan Kettering Cancer Center and from MIT are reporting the development of a new combination therapy that completely eliminates colon cancer, at least in laboratory mice. The technique is a type of radioimmunotherapy,...
An abdominal aortic aneurysm can have a number of related causes, and matrix metalloproteinases (MMPs) are one of those potential causes. MMP matrix enzymes have a useful role in a healthy body of breaking up the extracellular matrix during...
