NIH takes step to assess any possible risk associated with low-dose radiation exposure

01.02.2010
Researchers at the National Institutes of Health (NIH) Clinical Center are incorporating radiation dose exposure reports into the electronic medical record, an effort that they hope will lead to an accurate assessment of whether any cancer risk is associated with low-dose radiation exposure from medical imaging tests, according to an article in the February issue of the Journal of the American College of Radiology (JACR). The electronic medical record allows for the storage, retrieval, and manipulation of one's medical records.

There is much controversy surrounding diagnostic medical radiation exposure. "One widely publicized appraisal of medical radiation exposure suggested that about 1.5 to 2 percent of all cancers in the USA might be caused by the clinical use of CT alone," said David A. Bluemke, MD, lead author of the article and director of Radiology and Imaging Sciences at the NIH Clinical Center.

"Since there is no epidemiologic data directly relating CT scanning to cancer deaths, scientific assessment must instead rely on the relationship between radiation exposure and death rates from Japanese atomic bomb survivors. While the legitimacy of this approach remains debated, radiologists as well as clinicians may rightfully be confused by the ongoing controversy. Patients seeking medical help may legitimately question the rationale of, and any risks from, diagnostic radiology tests," said Bluemke.

Radiology and nuclear medicine at the NIH Clinical Center have developed a radiation reporting policy that will be instituted in cooperation with major equipment vendors, beginning with exposures from CT and PET/CT. "All vendors who sell imaging equipment to Radiology and Imaging Sciences at the NIH Clinical Center will be required to provide a routine means for radiation dose exposure to be recorded in the electronic medical record. This requirement will allow cataloging of radiation exposures from these medical tests," said Bluemke. In addition, radiology at NIH will also require that vendors ensure that radiation exposure can be tracked by the patient in their own personal health record. This approach is consistent with the American College of Radiology's and Radiological Society of North America's stated recommendation, that "patients should keep a record of their X-ray history."

"The cancer risk from low-dose medical radiation tests is largely unknown. Yet it is clear that the U.S. population is increasingly being exposed to more diagnostic-test-derived ionizing radiation than in the past," said Bluemke.

"While these steps themselves are not sufficient to allow population-based assessment of cancer risk from low-dose radiation, they are nonetheless necessary to begin a data set for this determination. The accumulation of medical testing doses of hundreds of thousands of individuals in the United States over many years will ultimately be necessary. We encourage all medical imaging facilities to include similar requirements for radiation-dose-reporting outputs from the manufacturers of radiation-producing medical equipment," said Bluemke.

The February issue of JACR is an important resource for radiology and nuclear medicine professionals as well as students seeking clinical and educational improvement.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
