New metamaterial-enhanced MRI technique tested on humans

Scientists from the Netherlands and Russia have designed and tested a new metasurface-based technology for enhancing the local sensitivity of MRI scanners on humans for the first time. The metasurface consists of thin resonant ...

New biosensor zymonic acid shows changes in pH value

Tumors, inflammation and circulatory disorders locally disturb the body's acid-base balance. These changes in pH value could be used for example to verify the success of cancer treatments. Up to now, however, there has been ...

Retired MRI scanner gets new life studying the stars

A team of researchers has successfully taken a magnet from a decommissioned MRI scanner used by a Brisbane, Australia, hospital for scanning patients, and recycled it for use in an experiment at CERN's ISOLDE facility.

Ultrasound scalpel destroys liver tumors

Focused ultrasound can effectively destroy tumor cells. Until now, this method has only been used for organs such as the prostate and uterus. At the European Congress of Radiology, Fraunhofer researchers will present a method, ...

Real-time MRI analysis powered by supercomputers

One of the main tools doctors use to detect diseases and injuries in cases ranging from multiple sclerosis to broken bones is magnetic resonance imaging (MRI). However, the results of an MRI scan take hours or days to interpret ...
