Reduced-dose gadobutrol vs standard-dose gadoterate for contrast-enhanced brain MRI

According to ARRS’ American Journal of Roentgenology (AJR), a reduced dose of gadobutrol is non-inferior to 100%-standard dose of gadoterate for contrast-enhanced brain MRI. “A 25% reduced gadobutrol dose demonstrated non-inferior efficacy versus standard dose gadoterate for contrast-enhanced brain MRI,” corresponding author Jan Endrikat of Germany’s University Medical School of…

Supertasters may have some innate protection against COVID-19

One of the biggest mysteries of the novel coronavirus is why it affects some people more severely than others. Now, a group of scientists has found that people who experience a greater-than-average intensity of bitter taste — known as “supertasters” — were less likely to become infected with, or become…

In a recent study, the researchers explored the distortions that bias our memory regarding the locations of…

Omega-3s may hold key to unlocking blood-brain barrier

Spectacular images of a molecule that shuttles omega-3 fatty acids into the brain may open a doorway for delivering neurological therapeutics to the brain. “We’ve managed to obtain a three-dimensional structure of the transporter protein that provides a gateway for omega-3s to enter the brain. In this structure, we can…
