Panel members included James A. Brink, M.D., professor and chairman of the Department of Diagnostic Radiology at Yale University School of Medicine in New Haven, Conn., and co-chairman of the joint Adult Radiation Protection Task Force cosponsored by the RSNA and the American College of Radiology (ACR); William R. Hendee, Ph.D., distinguished professor of radiology, radiation oncology, biophysics and bioethics at the Medical College of Wisconsin in Milwaukee; and Christoph Wald, M.D., Ph.D., executive vice-chairman of the Department of Radiology at Lahey Clinic in Burlington, Mass., and associate professor of radiology at Tufts University Medical School in Boston. The panel was moderated by Mary C. Mahoney, M.D., professor of radiology and director of Breast Imaging at the University of Cincinnati Medical Center and chair of the RSNA Public Information Committee.
"Medical imaging examinations are an invaluable, but complex, set of tools in the diagnosis and treatment of patients," Dr. Mahoney said. "With this panel, we hope to address recent concerns about imaging, clear up some misconceptions regarding risk, and inform the public about what's being done to ensure their safety when undergoing medical imaging exams."
The growth in medical imaging over the past two decades has yielded important and life-saving benefits to patients. Medical imaging has allowed millions of patients to avoid more invasive diagnostic and treatment procedures. However, overutilization of medical imaging examinations can be detrimental to patients by exposing them to unnecessary radiation. Between 1980 and 2006, the annual U.S. population radiation dose from medical procedures increased seven-fold, according to the National Council on Radiation Protection and Measurements.
"Imaging procedures conducted for the wrong reasons contribute to unnecessary costs and radiation exposure to patients," Dr. Hendee said. "Radiology is working to reduce unnecessary procedures, but some of the causes of overutilization are beyond radiology's influence."
Recent reports have drawn attention to the ionizing radiation associated with some imaging procedures, most notably CT. There is general agreement in the radiology community that certain imaging and radiation therapy procedures are associated with risks, which in each patient's case must be weighed against the benefit of the diagnostic information or treatment result one specific procedure may provide. Radiologists and medical physicists continue to work together to improve the safety of imaging exams by lowering radiation dose without sacrificing diagnostic quality. Efforts are also under way to better monitor patients' cumulative radiation exposure from multiple imaging exams over time.
To increase awareness of cumulative radiation dose and other radiation risks and to explore opportunities to improve patient safety through appropriate utilization, quality assurance and dose optimization, RSNA has partnered with the American College of Radiology (ACR), the American Association of Physicists in Medicine (AAPM) and the American Society of Radiologic Technologists (ASRT) to launch the Image Wisely™ initiative. Much like the Image Gently initiative did for pediatric radiology, Image Wisely was developed to educate imaging professionals, referring physicians and the public on the relative benefits and risks of medical imaging.
"Rising concerns about the radiation dose associated with medical imaging have prompted vigorous responses at many levels, but perhaps the most important response has been expanded educational activities focused on radiation dose monitoring and control," Dr. Brink said. "Imaging professionals must pledge to reduce the radiation dose as much as reasonably achievable, to seek accreditation of imaging facilities with careful attention to radiation dose monitoring and control, and to participate in dose registries that will allow imaging practitioners to benchmark their dose levels with peer institutions."
ImageWisely.org, directed at physicians and other medical professionals, was officially launched at RSNA 2010. The website's patient-directed content, which answers common patient questions about risks and benefits of medical imaging procedures, is available along with information on radiation exposure, contrast materials, anesthesia, radiation therapy procedures and other safety concerns on RadiologyInfo.org.
"These websites strive to provide the most comprehensive and up-to-date information about radiation safety from expert sources to help patients and their physicians make informed decisions when considering the use of powerful imaging tests which can potentially save lives, help determine whether a therapy is working or avoid an unnecessary surgery," Dr. Wald said.
Note: Copies of RSNA 2010 news releases and electronic images will be available online at RSNA.org/press10 beginning Monday, Nov. 29.
RSNA is an association of more than 46,000 radiologists, radiation oncologists, medical physicists and related scientists committed to excellence in patient care through education and research. The Society is based in Oak Brook, Ill. (RSNA.org)

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
