title: Reducing radiation dose in body CT: a primer on dose metrics and key CT technical parameters.
abstract: OBJECTIVE
  The purpose of this article is to describe how to interpret radiation dosi-metric data available on a body CT dose report and to explain the effects of key operator-chosen CT parameters on patient radiation dose.
  
  
  CONCLUSIONS
  To apply dose reduction strategies in body CT, radiologists must understand the information contained in the CT dose report and know the effects of key CT technical parameters on patient radiation exposure.
