Computed Tomography — An Increasing Source of Radiation Exposure

The number of computed tomographic (CT) studies performed is increasing rapidly. Because CT scans involve much higher doses of radiation than plain films, we are seeing a marked...

Estimated Radiation Risks Potentially Associated with Full-Body CT Screening

The authors provide estimates of lifetime cancer mortality risks from both single and annual full-body CT examinations. These risk estimates are needed to assess the utility of ...

Radiation Risks Potentially Associated with Low-Dose CT Screening of Adult Smokers for Lung Cancer

Given the estimated upper limit of a 5.5% increase in lung cancer risk attributable to annual CT-related radiation exposure, a mortality benefit of considerably more than 5% may...

Mass Screening With CT Colonography: Should the Radiation Exposure Be of Concern?

Estimated Risks of Radiation-Induced Fatal Cancer from Pediatric CT

The best available risk estimates suggest that pediatric CT will result in significantly increased lifetime radiation risk over adult CT, both because of the increased dose per ...

Cancer risks attributable to low doses of ionizing radiation: Assessing what we really know

High doses of ionizing radiation clearly produce deleterious consequences in humans, including, but not exclusively, cancer induction. At very low radiation doses the situation ...

Estimates of the cancer risks from pediatric CT radiation are not merely theoretical: Comment on “Point/Counterpoint: In x‐ray computed tomography, technique factors should be selected appropriate to patient size. Against the Proposition” [Med. Phys. <b>28</b>, 1543–1545 (2001)]

It is time to retire the computed tomography dose index (CTDI) for CT quality assurance and dose optimization

Arguing against the Proposition is Cynthia H. McCollough, Ph.D. Dr. McCollough is Associate Professor of Radiological Physics at the Mayo Clinic College of Medicine. She oversee...
