Context

CT has undergone tremendous technological improvements with incredibly diverse clinical applications. The result of these innovations has significantly increased utilisation. Concern for the risks associated with the exposure to ionising radiation has risen. Analysis based on survivors from the Hiroshima and Nagasaki atomic bombings has been one of the central methods to understand these risks. These analyses require estimations and extrapolations and thus controversy and doubts persist. There is consensus that children are particularly radiosensitive given their rapidly dividing cells and their life expectancies. Therefore, a study that attempts to determine the risks to children exposed to ionising radiation dose at levels comparable to current clinical practice is crucial to creating …
