A specially adapted magnetic resonance imaging (MRI) scanner can help physicians remove brain tumors and all of the residual cancer during one surgical procedure, according to a study published in the October issue of the journal Radiology. Using intraoperative MR-guidance, surgical strategy was changed in one out of four cases.
"Imaging during surgery provides intraoperative quality control. It presents valuable information during the procedure that allows the surgeon an opportunity to adjust the strategy," said lead author Christopher Nimsky, M.D., an associate professor at the University Erlangen-Nürnberg in Germany. Prior to intraoperative imaging, small parts of the tumor could be inadvertently missed. This tumor residue usually required repeated surgery, surveillance or further treatment.
The researchers reported their first clinical experience with intraoperative high-field MRI of 200 patients. They evaluated the extent of tumor removal depicted by intraoperative imaging and how surgical strategy was altered. The investigators found that imaging quality was indistinguishable between the pre- and intraoperative scans. In 27.5 percent of cases, intraoperative MRI impacted surgical strategy, often depicting additional tissue that needed to be removed.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
