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."

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
