“…Their practice was therefore heavily guided by subjective measures, and less guided by an objective measure of compression force. This was an important finding because the subjective measures applied in compression force can result in large inter and intra difference between practitioners, as found by Mercer 7,8 (2013). Whilst the results cannot be generalised to the whole population from this small sample the findings may well resonant with current practitioners and adds to the limited evidence base within this speciality.…”

“…While the influence of different amounts of compression force on visual image quality is currently disputed, 8 insufficient compression force may be detrimental to image quality and lesion visibility resulting in the potential for incorrect diagnoses. Standard texts suggest there may be a level of compression force beyond which additional compression forces cease to have any advantageous effect 9 and that additional compression force applied does have a marked effect on the woman's tolerance of the procedure and related discomfort 9 .…”

Compression force behaviours: An exploration of the beliefs and values influencing the application of breast compression during screening mammography

Introduction and backgroundBreast compression force during screening mammography requires a degree of practitioner knowledge and expertise to achieve optimum image quality and reduce the mean glandular radiation dose.1, 2 Whilst it is recognised that the application of compression force is an Whilst quantitative approaches give valuable data, a humanistic, qualitative, perspective is also required in order to fully understand this phenomenon in depth and to provide a unique insight in to the factors influencing how compression force is applied.Using a phenomenological approach this study investigated the experiences of, and the influences on the behaviour of, practitioners applying compression force in mammography. By exploring the individual and collective beliefs and values that influence compression force practice this paper seeks to identify 'how' and 'why' practitioners practice as they do. MethodologyQualitative research is an overall term for a group of approaches that is concerned with the investigation of experiences and behaviour, and the meanings and interpretations that people attach to these 12 . It is therefore an exploration of the natural setting; in this case the breast screening units in this study. An ethnographic approach of observing practice was initially considered but this was rejected as being too intrusive for the clients and potentially a contentious ethical issue. It was however recognised that by seeking the practitioners own

“…The variation in applied compression force in the XBSCP might have consequences for the quality of the programme, such as image quality, 25,26 radiation dose, 27-29 the female's experience of the examination 4 and reattendance. 5,6 Contradictory results have been reported regarding the effect of compression force on visually assessed image quality.…”

Objective: Compression is used in mammography to reduce breast thickness, which is claimed to improve image quality and reduce radiation dose. In the Norwegian Breast Cancer Screening Program (NBCSP), the recommended range of compression force for full-field digital mammography (FFDM) is 11-18 kg (108-177 N). This is the first study to investigate the compression force used in the programme. Methods: The study included information from 17,951 randomly selected females screened with FFDM at 14 breast centres in the NBCSP, during January-March 2014. We investigated the applied compression force on the left breast in craniocaudal and mediolateral oblique views for breast centres, mammography machines within the breast centres and for the radiographers. Results: The mean compression force for all mammograms in the study was 116 N and ranged from 91 N to 147 N between the breast centres. The variation in compression force was wider between the breast centres than that between mammography machines (range 137-155 N) and radiographers (95-143 N) within one breast centre. Approximately 59% of the mammograms in the study complied with the recommended range of compression force. Conclusion: A wide variation in applied compression force was observed between the breast centres in the NBCSP. This variation indicates a need for evidencebased recommendations for compression force aimed at optimizing the image quality and individualizing breast compression. Advances in knowledge: There was a wide variation in applied compression force between the breast centres in the NBCSP. The variation was wider between the breast centres than that between mammography machines and radiographers within one breast centre.
