A multicenter study of 821 patients referred for breast biopsy based on prior examinations that suggested cancer finds that while magnetic resonance imaging (MRI) distinguishes between benign and malignant breast tumors better than mammography, biopsies are still needed to confirm the diagnosis.
The study, called the International Breast MR Consortium, was carried out in 14 university hospitals in the United States and Europe, including Johns Hopkins, from June 1998 through October 2001. All patients underwent MRI exams prior to breast biopsy.
David Bluemke, M.D., Ph.D., associate professor of radiology at the Johns Hopkins University School of Medicine, led the Hopkins team that examined 200 of the 821 patients enrolled in the study and reviewed data from all study participants. MRI correctly detected cancer in 356 of 404 cancer cases, resulting in a sensitivity of 88.1%. It correctly identified as negative for cancer 281 of 417 cases without cancer, producing a specificity rate of 67.7%, compared to 52.8% for mammography.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
