CT screening uses a lower dose compared to standard CT scans. We strive to keep the dose between 1-2 mSv (millisieverts) or lower, although for individual patients it may be slightly higher than this value. As a comparison, average background radiation in the US is approximately 3 mSv/ year and in Denver, Colorado, due to the higher altitude it is 11.8. Another comparison is that the exposure of a low-dose CT scan is less than a mammogram which is below 0.6 mSv.
Our events include the semi-annual International Conference on Screening for Lung Cancer, and CME training courses on CT screening for lung cancer and its related issues.
