Diagnostic imaging includes various modalitiesthat use low-dose ionizing radiation. Modalitiessuch as magnetic resonance imaging (MRI) and ultrasound (U/S) are non-ionizing. However,modalities such as x-ray (XR) and computedtomography (CT) are considered as carcinogenic as they feature low-dose ionizing radiation [1], [2]. The risk ofcancer has been modelled via a linear, no-threshold (LNT) model and has been accepted by the Committeeon the Biologic Effects of Ionizing Radiation (BEIR), the United Nations Scientific Committee onthe Effects of Atomic Radiation (UNSCEAR), theInternational Committee on Radiological Protection (ICRP), and the...

Weconductedseveral literature reviewsusing the STARLITE method, to examine patient and non-radiologist physician knowledge regarding the risk of low-dose radiation, the patient physician dialogue and the sources of information they use, as well as the frequency and topics of the discussions.PubMed and MEDLINEdatabases were searched to include articles from2007 to 2017. A wide array of search terms wasemployed to identify articles based on the specificquestion to be answered. Peer-reviewed, original research articleswere the focus of the review. Three literature reviews were conductedto acknowledge each aspect and...

This survey confirmed that patients and non-radiologist physicians do not have a satisfactory level of low-dose radiation understanding. It also identified that patients do wish to be informed of the risk and have a discussion with their doctor, so a way to facilitate the discussion would be very beneficial.
