Scientists at the Research & Education Institute at Harbor-UCLA Medical Center (REI) are developing a new breast imaging diagnostic tool which will afford clinicians greater opportunities for detecting early stage breast cancers with greater certainty and help patients avoid biopsy in some cases. This detection method identifies breast lesions utilizing a radiopharmaceutical diagnostic imaging technology known as Tc-99 Sestamibi (MIBI) scintimammography. The procedure is based on a radioactive isotope being injected into a vein in the arm. Once absorbed into the body, the isotope can be seen by a group of special detectors, called gamma cameras, "marking" certain biological processes to locate a tumor.
Iraj Khalkhali, MD, principal investigator at REI, believes that the number of false negative (i.e., missed tumors) readings could be reduced if the limitations of contemporary gamma cameras were overcome. In one of his studies, Dr. Khalkhali found that three out of four false negatives were in the middle part of the breast and out of range of close camera contact. Dr. Khalkhali is currently pursuing research on improving scintimammography image quality through the design and development of a compact, thin gamma camera that affords easier access to all nodes and potential breast lesion sites.
"Access to breast lesions in the internal quadrants is especially important because these tumors may disseminate toward the internal mammary chain even when no axillary node is invaded. Easy access to all nodes and potential breast lesion sites will improve image quality and can be expected to improve the diagnostic accuracy of scintimammography, " said Dr. Khalkhali. "Although mammography is currently the standard early diagnostic screening tool, scintimammography has proven to be a highly effective adjunct in identifying lesions missed by mammography – particularly in women with dense breast tissue, low suspicion lesions on mammograms, pre-menstrual women with lumps in their breasts and women with locally advanced breast cancer," he added.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
