Early and accurate detection of oncological disease is critical to the treatment and, ultimately, survival of patients suffering from cancer. In an effort to determine the accuracy of an integrated PET/CT scanner with more traditional diagnostic imaging methods for whole-body, malignant tumors, researchers in Essen, Germany, compared the imaging results of the integrated FDG-PET/CT with CT images alone, PET images alone, and CT and PET images viewed side-by-side.
The scientists theorized that the new technologically superior, dual-modality PET/CT would yield more accurate readings of tumor staging than previously used image capture methods. The German team presented their findings at the Society of Nuclear Medicine’s 51st Annual Meeting.
The study included 260 patients with a variety of oncological diseases. The patients underwent whole-body imaging, and the results of the four image sets--CT alone, PET alone, CT and PET viewed side by side, and integrated PET/CT--were evaluated by different reader teams according to the TNM (Tumor-Node-Metastasis) staging system. Histopathology and follow-up clinical assessment of the patients served as the baseline standard of reference.

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«...
The well-known representation of chemical elements is just one example of how objects can be arranged and classified

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...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
