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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
