Smaller lymph nodes commonly seen on abdominal CT scans in "healthy" people are not clinically significant and require no further imaging, a new study confirms. The study was performed because there is no standard as to what should be done about these patients so they often undergo additional testing to rule out inflammation, cancer or other diseases.
Researchers examined CT scans of 120 patients treated in the emergency room following blunt abdominal trauma that had no history of an illness that may result in lymphadenopathy. Other than evidence of trauma, the patients were healthy and CT scans were normal, said Brian C. Lucey, assistant professor of radiology at Boston Medical Center, and lead author of the study. "We found that 39% of these patients (47 of the 120) had mesenteric lymph nodes (found in the area of the abdomen near the small intestines) averaging in size about 5 mm," Dr. Lucey said. "We examined hospital records a year after each of these patients had been examined, and there was no evidence that any of them had developed disease," he said. Dr. Lucey notes that there is the possibility that patients could have gone to other institutions for further medical care, however, "we feel it is reasonable to believe that this group of patients is representative of the healthy population."
"MDCT scanners and PACS computer workstations allow us to more clearly distinguish lymph nodes from vessels and other internal structures and thats why we are seeing them more often," Dr. Lucey noted. "Multiple small nodes scattered throughout the abdomen are common, and follow-up imaging isnt needed" he said. However, if there are large clusters of lymph nodes or the patient has a history of cancer, then follow-up imaging may be necessary, Dr. Lucey said.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

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...
