Research output: Contribution to journalReview article

Abstract

OBJECTIVE. The purpose of this article is to describe how to interpret radiation dosimetric data available on a body CT dose report and to explain the effects of key operator-chosen CT parameters on patient radiation dose. CONCLUSION. 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.
