Image evaluation systems are used to evaluate mammographic image quality and must be reliable and valid. This study set out to investigate radiographers' perceptions of the current image evaluation systems such as the PGMI as well as their interpretation of criteria relating to the presentation of the pectoral muscle in the mediolateral oblique view.</p></div><div><h3>Method</h3><p><span>A survey method was employed for this exploratory study as a way of collecting data from the largest possible sample. Surveys were distributed to radiographers employed in all different types of work in </span>mammography. Following collation of responses descriptive statistics were developed. Thematic analysis was applied to the responses to the open-ended questions.</p></div><div><h3>Results</h3><p>One hundred and sixty eight surveys were returned. The questionnaire responses were grouped into two categories: image evaluation systems and the presentation of the pectoral muscle. Overall the study results demonstrate variations in Australian radiographers' practice when evaluating mammogram images.</p></div><div><h3>Conclusion</h3><p>The study demonstrated worrying variations in the interpretation of criteria in current image evaluation systems. Inconsistent interpretation of criteria relating to the presentation of the pectoral muscle increases the risk of breast tissue not being included in the image. This study has provided evidence for the need for clearly defined criteria using objective measures so that the subjectivity of interpretation is minimised.</p></div>","PeriodicalId":100505,"journal":{"name":"European Journal of Radiography","volume":"1 1","pages":"Pages 12-21"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ejradi.2008.11.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81440809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calculated doses were found to be about 12.5% (range 8.9–13.3%) higher than doses obtained with thermoluminescence dosemeters (TLD). This level of discrepancy was about 4% higher than the value reported in the literature. Radiographic/technical quality was rated at 53.7% while image quality obtained against a standard image according to the European guidelines was rated with an above average score (58%). Notable variation between the hospitals was observed and the need for optimization highlighted in technical areas like </span>collimation<span>, film processing and in patient dose reduction using better exposure techniques. This study presents patient entrance doses and image quality in hospitals where such data was not existing and could therefore be used as a basis for future studies in dose and image quality, towards the development of local and national reference parameters. The mathematical method, though highly susceptible to errors, can be employed until dose monitoring equipment become more accessible.</span></p></div>","PeriodicalId":100505,"journal":{"name":"European Journal of Radiography","volume":"1 1","pages":"Pages 30-36"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ejradi.2008.09.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81790047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
