If a mammogram or sonogram suggests that a woman has breast cancer, an MRI should be done to help determine whether there actually is a cancer and if so, what are the woman’s best treatment options, a new study shows. The study, done in a large community hospital, found that MR images, which were acquired and analyzed in a specific way, can help identify if a lesion is benign or malignant and can show cancers that would otherwise be missed.
“This is the first time a prospective study has been done that shows that MRI (using a contrast agent) can work in a real life community setting - the setting in which most breast cancer patients are diagnosed and treated,” said Jonathan I. Wiener, MD, lead author of the study. The study included 65 patients who had “highly suspicious” findings on mammography or sonography and were believed to be candidates for breast conserving treatment. Nineteen of the patients did not have a suspicious lesion on MRI, and when these women were biopsied, it turned out they did not have cancer, said Dr. Wiener. Many of those patients could have avoided having a biopsy at all, he said.
In addition, MRI detected 23 additional cancers in the 44 patients that actually had a breast cancer (either in the same breast as the primary cancer and or in the opposite breast) that were not detected on mammography or sonography. Because of the additional information provided by MRI, and subseqently confirmed by pathological analysis of the biopsy specimens, it was recommended that eight women have a mastectomy rather than breast conservation treatment. “About 15% of breast cancer patients have a recurrence of their disease. We don’t know precisely why cancer returns in previously thought to be adequately treated breast cancer patients. One of the reasons could be that many of the cancers may be missed initially with only a conventional work up with mammography and ultrasound. The addition of MRI will improve the accuracy of breast cancer diagnosis,” Dr. Wiener said.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
