Image Wisely, a joint initiative of ACR, RSNA, ASRT and AAPM, provides information to the medical community to promote radiation safety in medical imaging.

Computed Tomography

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!

Radiologists can serve their patients by championing the life saving benefits of lung cancer screening with low radiation with low radiation dose CT, particularly to the newly eligible population.
