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: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
