To the Editor The American College of Radiology (ACR) has for decades worked to reduce unwarranted imaging and lower radiation dose. We wish to update the information in a recent editorial by Smith-Bindman and Bindman.1
The reference cited on growth of computed tomography (CT) use includes data only through 2010.
