In a possible first, researchers at Stanford (Calif.) Medicine found a non-invasive imaging method to visualize senescent cells. “As we age, we accumulate senescent cells. These are like ‘zombie cells ...

A doctor orders an X-ray for a patient with a knee ache. The bones look fine, and the most likely prognosis is arthritis, ...

A metal-free MRI contrast agent has been developed that could be safer for certain patients. The compound contains organic molecules called nitroxides instead of metal and may be used to generate more ...

A new magnetic resonance imaging (MRI) contrast agent being tested by researchers at Case Western Reserve University not only pinpoints breast cancers at early stages but differentiates between ...

Medically reviewed by Rony Kampalath, MD Key Takeaways An MRI with contrast uses a special dye to make blood vessels, organs, and tissues stand out more clearly.The dye used in MRI with contrast ...

Experiments in dogs, rabbits and monkeys show the efficacy and biocompatibility of a new MRI/MRA contrast agent in detecting stroke. This T1 MRI contrast agent based on ultrasmall iron oxide ...

Scientists at the Institute of Chemistry have developed a new type of contrast agent for magnetic resonance imaging (MRI)—bovine serum albumin nanoparticles doped with manganese (II) ions. The results ...

CAMBRIDGE, MA -- To enhance the visibility of organs as they are scanned with magnetic resonance imaging (MRI), patients are usually injected with a compound known as a contrast agent before going ...
