CT Radiation and the Risk of Cancer
The paper covers three points. First, the doses we use for CT are higher than widely reported and are higher than what is needed for diagnosis and should be reduced. Second, these doses are in the range where ...

Trends of CT Utilization in North America Over the Last Decade
Given the improvements in technology and usefulness of CT for diagnosis and therapeutic-planning, the growth in CT utilization is not surprising. Current estimates are that more than 85 million CT scans are pe...
