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: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
