“…The finding of ultrasound association with ionising radiation is slightly higher than the findings in the literature on physicians. Prior studies on physicians report a 4-14% incorrect association for ultrasound [8]- [11] [17]. This indicates lack of knowledge likely resulting in requesting less number of ultrasound(almost 59.5% consultants request ultrasound ordering less than one test per day) Had they been known about the lack of ionising radiation in ultrasound they could request more number of ultrasound wherever needed thus reducing the load of radiation exposure on patient.…”

“…Over the past decade many studies have investigated physicians from varying specialities on their knowledge of radiation dose and associated risks, and most studies have disappointing results [8][9] [10]. It is important that the consultants who request imaging are well trained in deciding whether diagnostic imaging is indicated, but also have an accurate knowledge of the associated risks.…”

Objective: To assess the knowledge, awareness and attitude of consultants about radiation hazards in diagnostic radiology and to describe their practice with regard to informing patients at risk. Methods: Prospective questionnaire based observational study performed between July and December 2013, conducted in two different university education and research centres, two private research hospitals and four outpatients' clinics of Central India. The questionnaire was administered to 220 consultants. Data was analysed using EPI INFO 2007 Results: 205 consultants (93%) completed the questionnaire. The overall mean knowledge score was 59.3%. Mean knowledge score was 60.23% for senior doctors and 56.89% for junior doctors, but this was not found to be significant (P=0.2107). Almost more than three-quarters of consultants (91.2%) underestimated the radiation dose in CT scan of abdomen. Most doctors (75%) though that one CT scan increase the life time risk of developing cancer and 25% consultants said that there was no increased cancer risk. MRI and Ultrasound was wrongly associated with ionizing radiation by 24.39% and 26.83% of consultants respectively. The frequency at which doctors would inform patients of the risk of radiation varied greatly depending on the clinical scenario. Conclusions: There was lack of awareness and relatively poor knowledge among the consultants which may lead them to request more tests and thus increasing the radiation exposure load on the patients. Consultants should receive education, and the request form should display radiation dose and associated risk.

“…According to some experiences published in the BMJ [39,40], doctors working in the UK National Health Service have insufficient knowledge about radiation protection, despite serious continuous education programmes for health professionals and a widely available publication for referring physicians entitled ''How to make the best use of the diagnostic radiology department'', in which the practice of dose reduction is extensively described [41].…”

CT exposure in adult and paediatric patients: a review of the mechanisms of damage, relative dose and consequent possible risks

et al. 2014

An increase has been observed not only in the absolute number of CT examinations but also in the length of coverage and number of scanning phases, with the result that exposure to ionising radiation from CT is becoming an increasingly serious problem. The extent of the problem is not entirely known and cannot be adequately addressed without proper knowledge of all the phases that leads to the effective dose calculation. In light of the growing awareness of the issue of ionising radiation dose and the possible risk for the individual and the population, there is a need for radiologists, medical physicists and radiographers to play an active role in dose management. In this review, the authors try to delineate the problem in a consequential and multifaceted way: radiation-patient interaction, possible mechanisms of damage, main CT dose units, risk and its quantification in the population, with the aim of optimising the acquisition dose without diagnostic drawbacks. For an ''up-to-date'' use of CT, radiologists must know the dose concerns for the single patient and population, and use the CT apparatus with the best dose care; substitute CT with other diagnostic techniques when possible, especially in children; reduce the number/extension of scans and phases, and the dose in single scans and single examinations.

“…When assessed with regard to their knowledge of radiation exposure and the associated risks, clinicians consistently perform disappointingly with significant underestimation of typical radiation exposures associated with different diagnostic imaging studies [47][48][49][50]. The European Council issued the Euratom directive in 1997 and advised integration of a module in radiation protection, into the curriculum of medical schools in an effort to raise awareness [51].…”
