Community hospital implements successful CT radiation dose reduction program

01.08.2011
In an effort to reduce the radiation dose delivered by computed tomography (CT) scans, staff at a community-based hospital developed a comprehensive CT radiation dose reduction program which has allowed them to reduce the radiation dose delivered by CT scans at their facility, according to an article in the August issue of the Journal of the American College of Radiology.

CT is an essential tool for the accurate diagnosis of disease and injury but is associated with radiation doses higher than those of conventional X-ray imaging. Although high doses of radiation are known to increase the risk for cancer, the effects of the much lower doses used in diagnostic imaging are not conclusively known.

"This uncertainty makes it good practice and in the interest of patient safety for medical facilities to reduce radiation dose to the lowest level necessary for accurate diagnosis," said Mary Ellen Jafari, MS, DABR, lead author of the article.

Staff at Gundersen Lutheran Health System, a physician-led health care system headquarted in La Crosse, Wisconsin, developed a comprehensive CT radiation dose reduction program.

"The focus of our program is on easily implemented, practical actions. Prioritized for dose reduction actions are high-dose examinations, patients scanned repeatedly for chronic conditions, pediatric patients and pregnant patients," said Jafari.

Staff implemented practical actions on the basis of a system of key strategies, including ensuring proper CT scanner functionality and appropriately trained staff members, monitoring and evaluation of radiation dose, optimization of CT acquisition protocols and education of referring physicians and patients. CT acquisition protocol changes demonstrably reduced effective dose. For example, a low-dose renal stone CT scan protocol reduced effective dose by 64 percent. Other dose reductions varied by protocol type.

"It is good practice and in the interest of patient safety for medical facilities to reduce CT radiation dose to the lowest level necessary for accurate diagnosis. Despite staffing and time limitations, CT radiation dose can be reduced at smaller medical facilities such as community hospitals by implementing practical actions on the basis of a system of key strategies," said Jafari.

Gundersen Lutheran Health System is accredited in CT imaging by the American College of Radiology.

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

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
