TL;DR: Evidence is found that CT-related radiation exposure increases brain tumor risk following exposure to low-dose ionizing radiation from CT scans in childhood, and incidence of brain tumors was higher in the cohort of children with CT scans, requiring cautious interpretation of the findings.

TL;DR: The risk related to routine usage of CT in clinical care is small and a life-limiting disease, such as CF, lowers the risk of radiation-induced cancer, so the use of CT should always be justified and the radiation dose should be kept as low as reasonably achievable.

TL;DR: CT scores from end-expiratory and end-inspiratory CT alone may be sufficient for monitoring CF-related lung disease, suggesting that radiation dose reduction by up to 75% may be necessary for a single investigation.

TL;DR: DS spiral CT coronary angiography performed with adaptive ECG pulsing results in preserved diagnostic image quality and performance independent of HRF or HRV at the cost of limited dose reduction in arrhythmic patients.

TL;DR: A high-pitch spiral CT coronary angiographic protocol should be applied in patients with regular and low (<55 beats per minute) heart rates; a sequential protocol is preferred in all others.
