DLP is derived from CTDIvol, but incorporates a scan length component. Both function as reasonable proxies for absorbed dose but do not represent the actual patient dose.

Initially, the Corporate level Aggregate reports were not… Read More
At my direction, our facility began submitting CT dose data to the ACR’s Dose Index Registry® (DIR) in early 2013. During the following months I learned to use the DIR to identify dose reduction opportunities, and lower our CT doses. In August 2105 The Joint Commission (TJC) updated its diagnostic imaging Elements of Performance requiring… Read More
