This paper reviews the reasons why multi-slice CT scanners may give patients higher dose than their single-slice predecessors and discusses the type of optimization of multi-slice scan protocols that may be undertaken to keep patient doses to acceptable levels without compromising image quality. It also provides estimates of patient effective dose values and dose length products for typical procedures and briefly discusses the implication that these dose values have for the induction of possible stochastic effects.
