The accuracy and intrinsic safety of MRI in diagnosing abdominal and pelvic disease in pregnant women with acute abdominal or pelvic disease make it an excellent choice for the evaluation of these patients, a new study from researchers at the University of North Carolina Hospitals, Chapel Hill, and the University of San Diego Hospitals in California says.
In the study, MRI was used to image pregnant patients with acute abdominal or pelvic pain. Afterwards, each patient’s clinical course was closely followed. According to the authors, the prospective MRI interpretations correlated “extremely well” with clinical and surgical findings, and MRI accurately depicted several disease processes including appendicitis, pancreatitis, uterine fibroids and ulcerative colitis.
Safety is an important consideration in imaging pregnant patients, study authors said. “Instead of ionizing radiation, which is used to produce conventional x-ray images and CT scans, MRI uses a strong magnetic field and radiofrequency pulses to produce images. Ionizing radiation is a known carcinogen, whereas magnetic fields and radiofrequency pulses are not associated with cancer or fetal malformations,” said Katherine R. Birchard, MD, of the University of North Carolina Hospitals and lead author of the study.

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
