A new magnetic resonance imaging (MRI) technology reduces brain-imaging time from 20 minutes to three minutes while maintaining accuracy and decreasing patient discomfort, according to early research results presented at the 89th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA).
"The three-minute head scan is as good as the 20-minute version, and in some instances better because stroke patients may be distressed and move around," said study co-author, Jonathan H. Gillard, M.D. "Pictures taken in a shorter period of time are less susceptible to degradation from the patient moving during the scan." Dr. Gillard is a lecturer and honorary consultant neuroradiologist at Addenbrookes Hospital, University of Cambridge in England, where the study is ongoing.
To be successful, treatment with intravenous thrombolytic (clot-busting) drugs must typically begin within three hours after stroke onset. Interventional radiology has increased the critical treatment window through the use of catheters that deliver the drugs directly to the clot in the brain, but every minute counts. Therefore, it is essential that stroke patients be diagnosed quickly, so that treatment can begin. Computed tomography (CT) is the usual method for diagnosing stroke, because it only takes a few minutes, compared to 20 minutes with conventional MRI. However, unlike MRI, CT does not identify the parts of the brain that are at risk of damage.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
