(DIAGNOSTIC IMAGING) – Despite what has already been an illustrious career in health care, now is not the time to sleep on computed tomography (CT). Fifty years in, CT remains a cornerstone of medical imaging, aiding not only in diagnosis of disease or trauma, but also in helping to plan and guide therapeutic interventions as well as monitor their outcomes.
Withstanding the test of time and new technology, CT has also weathered bouts of criticism over the years. Although questions about overuse and radiation dose exposure have at times hindered its role, the risk/benefit ratio conversation nearly always tips towards the benefits of the modality, with its ability to quickly answer questions that might otherwise lead providers and patients down a road filled with a multitude of less specific—and so-called less ‘risky’—tests.
To help address some of these questions and improve education around dose, the American Association of Physicists in Medicine (AAPM) in 2010 formed the Alliance for Quality Computed Tomography, which provides several educational and informational resources, including a CT Dose-Check, up-to-date CT imaging protocols for both adult and pediatric patients, as well as CT dose and automatic exposure control educational materials.
