A technique that combines high-level magnetic resonance imaging (MRI) with a new spectroscopic method may result in an accurate, non-invasive way to make breast cancer diagnoses. In this technique, MRI is used to detect breast lumps, while spectroscopy measures molecules known to accumulate in cancer cells.
According to a study in the Nov. 21 online version of the journal Magnetic Resonance in Medicine, researchers at The Cancer Center at the University of Minnesota have developed a magnetic resonance spectroscopy (MRS) method that quantifies breast tissue levels of choline (tCho) compounds, which the study found to be elevated in malignant lesions. Previous investigations of the diagnostic utility of MRS did not quantify tCho levels in breast masses, which limited the ability to differentiate between benign and malignant lumps detected by MRI.
"We found tCho concentrations to be significantly higher in malignancies than in benign lumps and normal breast tissues using this quantitative method," said lead investigator Michael Garwood, Ph.D., professor of radiology and Cancer Center member. "Using high magnetic fields and this spectroscopic technique may produce a powerful way to diagnose breast cancer and to monitor its response to treatment. We hope this technique will eventually be used to avoid unnecessary biopsy."

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...
