Developing CT protocols to maximize diagnostic yield while minimizing dose
Image Wisely is a joint initiative of the American College of Radiology, Radiological Society of North America, American Society of Radiological Technologists and American Association of Physicists in Medicine.
The 2009 National Council on Radiation Protection and Measurements, Report No. 160 — Ionizing Radiation Exposure of the Population of the United States — showed that medical exposure to patients is one of the largest sources of radiation exposure to Americans, nearly equaling the exposure from background sources. Computed tomography is the largest source of medical radiation exposure.
The benefits of computed tomography are immense and certainly exceed the risks. However, this is only true when they are ordered appropriately and studies are optimized to obtain the best image quality with the lowest radiation dose. And be sure to take the pledge to Image Wisely!
