Digital radiography newsTaking the chance at the National Institutes of Health's "Summit on Management of Radiation Dose in Computerized Tomography (CT)": Toward the Sub-mSv Exam, the Medical Imaging & Technology Alliance (MITA) affirmed its commitment to safe, appropriate and effective medical imaging technology and encouraged continued stakeholder collaboration to minimize radiation exposure.

Dave Fisher, Executive Director of MITA, ensured that "Medical imaging manufacturers have been reducing radiation dose for CT scans for decades through technological innovations." Technological investments through imaging manufacturers have decreased radiation dose for some procedures by up to 75%, while maintaining the quality of images. Today's screening provides highly personalized, non-invasive care that can be significant with the age of each patient, weight and other unique factors.

Fisher mentioned that "As we move forward, it is the responsibility of the entire imaging community to work together to continue this effort. As manufacturers develop new radiation reduction features, we intend to continue working with other stakeholders to provide proper training, adopt appropriateness criteria and collect CT dose data for benchmarking".

MITA members have taken the lead on an industry-wide effort through its CT Dose Check Initiative in order to improve and implement additional patient protection features for CT equipment. These features include a mechanism to alert technologists before performing a scan if the dose is higher than expected and a dose-reporting DICOM Standard to facilitate more robust databases.

Rich Mather, PhD, Senior Manager, Clinical Programs Toshiba Medical Research Institute, who participated in the summit, explained, "Our focus is to continue to invest in research and development that will bring more advanced technologies to market. Efforts like the CT Dose Check Initiative are designed to help clinicians use these technologies in the safest way possible to protect patients."

Moreover, MITA enhances mandatory accreditation of screening facilities and the application of appropriateness criteria in a wider scope to promote the use of screening services.  In addition to the efforts of manufacturers, medical professionals and imaging providers, regulatory policymakers are another critical stakeholder for continued improvement in the reduction of dose. Fisher noted, "Regulators play an important role in the imaging innovation cycle. Timely review and clearance of CT equipment with new radiation reduction features is essential for patients to have access to these technologies."
