The first patient scans from a custom-built scanner combining positron emission tomography (PET) and computed tomography (CT) technologies indicate that these scans could significantly improve breast cancer imaging capabilities and lead to more targeted treatment options, according to researchers at SNM's 55th Annual Meeting. The prototype scanner is designed to help physicians determine stages of breast cancer in patients already diagnosed with the disease, rather than as a mammography screening tool.
"The use of dedicated breast PET/CT scanners could really open up new possibilities in treatment for women with breast cancer," said Ramsey Badawi, assistant professor of radiology, University of California–Davis Medical Center, Sacramento, and investigator for the study, First Human Images from a Dedicated Breast PET/CT Scanner. "Using this noninvasive technology, physicians can get much more accurate images of tumors—especially small tumors—than conventional full-body PET scans. This will enable physicians to determine the stage of the cancer and determine courses of treatment more accurately."
In addition, the technology could eventually be used to detect early whether drug treatments are effective in individual patients. "One great advantage for doctors will be to better plan breast cancer surgeries," said Badawi. "Using a PET/CT scan, doctors should be able to determine whether drug treatments are working before performing surgery, thus eliminating unnecessary mastectomies. Medical professionals will also have a much better sense of the exact location and size of tumors."
The technology also can be used to measure the effectiveness of new drugs and molecular imaging agents for detecting and treating breast cancer, another important component to advancing individualized medicine for patients. In addition, the dedicated breast PET/CT scanner can detect the difference between malignancies and benign tissues such as cysts or scars, eliminating many unnecessary biopsies.
The prototype breast PET/CT scanner studied by Badawi and his team consists of two adjustable planar heads. Patients lie prone as the PET and CT systems rotate around the freely suspended breast. PET and CD data are used to produce detailed three-dimensional images. Many women could also find the new technology more comfortable, because it does not require the breast to be compressed during the scan.
The first patient to be scanned with the dedicated breast PET/CT scanner was a 49-year-old woman with a palpable mass on her right breast. The dedicated breast PET/CT scan accurately detected breast cancer, which was later confirmed by biopsy. The results indicate that PET and CT images of the uncompressed breast are accurate and provide clinically relevant data.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
