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.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
