“…Given that women with large breasts tend to receive higher compression force compared to women with small breasts, higher compression force is related to higher absolute and lower percent dense volume. Use of site specific compression force might have influenced the strength of the correlation between compression force and breast volume as a wide compression force variation between the Norwegian breast centres has been shown in a recent study [24].…”

“…Branderhorst et al [45] found a number of factors contributing to the variation in compression, including the pain threshold of the woman, the radiographer’s sensitivity to pain expression, the uncertainty or inaccuracy in estimating the pressure on the breast and the radiographer’s opinion of what is a good compression. Some authors [46–48] suggest the existence of local compression culture related to the radiology department. Recent research results about the adverse effects of excessive compression force on the participation rate of breast cancer screening and on image quality need to be taught in the radiographer curriculum.…”

ObjectivesThis pilot study aimed to characterize and compare radiographers’ mammography practice, including quality control and continuous professional development in five European countries.MethodsOnline survey was performed to collect data regarding participants’ profile, institution’s profile, mammography practice, quality control and continuous professional development. The questionnaire was sent to clinical radiographers working in Estonia, Finland, Norway, Portugal and Switzerland. Descriptive statistical and subgroup analyzes were performed.ResultsThe amount of returned questionnaires was 140. Most respondents were female (92%), having radiography bachelor. The majority (89%) of radiographers was working with full-field digital mammography. The majority (97%) of mammography images were acquired using AEC, and half of the radiographers were using dose saving programmes suggested by the manufacturers. The most typical (50%) compression force ranged from 8 to 11 kg. Part of the radiographers (44%) did not know if their practice followed specific guidelines. The most challenging tasks in mammography identified by radiographers were patient positioning (86%), coping with pain (88%), managing anxiety (83%) and imaging breast implants (71%). The majority (88%) of the respondents undertook continuous professional development activities.ConclusionsThe mammography practice varies across the five countries. We found country-specific traits related to mammography image acquisition, patient-centered care and quality management procedures. The lack of evidence-based knowledge suggests the importance of well-designed studies on these topics. The variability found in this pilot study encourages radiographers to question their own practice and teachers to review and revise the training programmes. Validation in larger studies including more countries is needed.

“…This method has led to a decrease in the breast cancer mortality rate by 20 to 40% (2). Compression is used in mammography and it is applied using a compression paddle to fi x and compress the breast, which facilitates a better signal-to-noise-ratio, the higher homogeneity of the fi eld and thus a high-quality diagnostic mammogram, as well as a lower average glandular dose (3,4). The breast is essentially composed of fatty, connective and glandular tissue.…”

Purpose: To determine whether breast thickness decreases with menopause after the reduction of glandular tissue. We also wanted to know how the decrease in breast thickness affects the compression force and the average glandular dose. Methods: In this project, we collected data regarding the compression force, breast thickness and mean glandular dose of 300 patients who had mammographic imaging in two views: CC (craniocaudal) and MLO (mediolateral oblique) view. The data were divided into three age groups: 100 patients aged 50 to 55, 100 patients aged 60 to 65 and 100 patients aged 70 to 75 years. We used basic statistical tests for measurement purposes, while we used the Shapiro–Wilk test to check normality and the Kruskal–Wallis test to compare the differences. Results and discussion: We presented the results and comparisons in the tables and box plot graphs for CC and MLO views of the left and right breast for compression force, breast thickness and MGD. In the CC view of the both breasts, we found that there were statistically signifi cant differences in thickness between groups 1 and 3, and differences in MGD between groups 1 and 2, and 1 and 3. In the MLO view of both breasts we found that compression force does not increase with the age of patients, which can be attributed to the different size and density of breasts, and different compression force. Higher compression force results in lower MGD and breast thickness. Conclusion: In the CC view of left and right breast, there is no statistically signifi cant differences in compression force, but thickness and MGD changed between some groups. In the MLO view, only MGD changed. For further research, we recommend taking measurements on a larger sample, and concurrently considering and examining other factors that may affect breast thickness, compression force and MGD.
