Diagnostic reference level quantities for adult chest and abdomen-pelvis CT examinations: correlation with organ doses

Abstract

Key points 1. DRL quantities and target-organ doses can support guidance’s to optimization criteria. 2. Organ doses inside imaged area are higher than in other regions. 3. Statistical significance between organ doses and the DRL quantities are presented. 4. Results reinforce the importance on the adequate choice of the scan length.
