The study, which is being presented during the American Roentgen Ray Society Annual Meeting on May 3 in Chicago, found that radiologists using MRI could correctly identify the primary site of cancer in 79% of cases (38/48 patients) when biopsy results are inconclusive.
Endometrial and cervical cancers are common cancers in women, said Heather He, MD/PhD, of MD Anderson Cancer Center in Houston, where the study was conducted under the direction of Dr. Iyer and Dr. Bhosale. "In about 3% of the cases, there is difficulty determining the primary cancer site," she added. "Knowing the primary cancer site means that we can give the patients the most appropriate therapy and save some patients from unnecessary surgery," Dr. He said.
Two radiologists read the images as part of the study – one with five years experience and one with 18. Their diagnoses matched most of the time, which means that the readers' experience didn't have much of an impact on the study results, said Dr. He. "MRI can be applied on a broader scope; you don't have to have someone on staff with extensive experience to be able to offer this imaging service," she said.
The study also examined various MR sequences to determine which one was the most useful in making a diagnosis. "We found that sagittal T2 FSE weighted sequences and 2D and 3D T1 weighted dynamic enhanced sequences are the most helpful," Dr. He 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...
