“… 10 Presumably, the excellent intra- and inter-rater reliability of compressed breast thickness may be explained by the radiographer’s consistent subjective assessment of the breast. Radiographers’ subjective breast compression behaviors 18 and perceptions of mammography methods in mammographic screening and diagnostic mammography 30 have also been investigated in qualitative studies, with some radiographers reporting that they applied breast compression based on breast characteristics rather than numerical values for applied force 18 —that is, a subjective assessment and perception of the breast tissue and its characteristics at compression influenced the breast compression. 18 , 30 It is thus reasonable to argue that the radiographer’s subjective assessment of breast compression helped to provide the excellent intra- and inter-rater reliability of compressed breast thickness reported in our study.…”

Background Ensuring equivalent and reproducible breast compression between mammographic screening rounds is important for the diagnostic performance of mammography, yet the extent to which screening mammography positioning and compression is reproducible for the individual woman is unknown. Purpose To investigate the intra- and inter-rater reliability of breast compression in screening mammography. Materials and Methods Eleven breast-healthy women participated in the study. Two experienced radiographers independently positioned and compressed the breasts of each participant in two projections—right craniocaudal and left mediolateral oblique—and at two time points. The spatial pressure distribution on the compressed breast was measured using a pressure sensor matrix. Applied force, compressed breast thickness, force in field of view, contact area, mean pressure, and center of mass (anterio-posterior and mediolateral axes) were measured. The reliabilities of the measures between the time points for each radiographer (intra-rater reliability) and between the radiographers (inter-rater reliability) were analyzed using the intraclass correlation coefficient (ICC). Results Intra- and inter-rater reliabilities from both projections demonstrated good to excellent ICCs (≥0.82) for compressed breast thickness, contact area, and anterio-posterior center of mass. The other measures produced ICCs that varied from poor (≤0.42) to excellent (≥0.93) between time points and between radiographers. Conclusion Intra- and inter-rater reliability of breast compression was consistently high for compressed breast thickness, contact area, and anterio-posterior center of mass but low for mediolateral center of mass and applied force. Further research is needed to establish objective and clinically useful parameters for the standardization of breast compression.

“…This gap can impact on radiographers and radiologists' activities considering that is important to know what should be demonstrated on the image to select the most suitable protocol and to achieve examination goals. Not having a level of image quality that allows for the analysis of all relevant anatomy of the breast with implants means the diagnosis of breast pathologies can be compromised [48].…”

Aims:To identify image quality criteria that can be applied to assess breast implant (BI) mammograms according to radiologists and radiographers' perspectives and to explore the level of agreement about criteria priority. Methods: A two-round Delphi method using a questionnaire was applied to identify the level of agreement between experts, asking them to rank each image criteria available for mammography according to 4 possible answers (1 = need to have, 2 = nice to have, 3 = not pertinent/appropriate, 4 = do not know). Criteria for craniocaudal (CC), mediolateral-oblique (MLO) and lateral (ML), with and without Eklund manoeuvre, were included. This process was repeated after removing the less relevant criteria. Results: Between first and second rounds, different results were obtained regarding the criteria to assess CC and MLO images. Details for anatomic areas were considered the most relevant by radiographers during the first round, while general criteria were prioritised during the second round. Radiologists focused more on analysis of the spread of the breast tissue, if the breast was aligned with detector's centre and level of contrast. The analysis of implant flow, the BI anterior edge and the maximum retropulsion of BI when Eklund manoeuvre is performed were the specific aspects of BI imaging considered as relevant for assessment. Conclusions: The importance of each criterion used to assess BI mammograms was not the same between radiographers and radiologists, suggesting the two groups of experts are looking for different requirements from the image. Further education and training is necessary to align strategies for assessing BI mammograms, and some criteria need to be adapted to reduce subjectivity.

“…positioning of the patient, positioning of the detector, and compression. A fourth category, compliance, also emerged during the analysis work and was identified by the radiographers as being an important factor to be able to succeed with positioning and compression [6].…”
