Achieving mortality reduction in breast cancer patients requires high-quality mammography screening. Even though an institution has satisfied the requirements proposed by the Subcommittee for Imaging Unit Evaluation, it does not mean that all mammograms at the institution are of high quality and good for reading.<BR>At the Cancer Dection Center, Miyagi Cancer Association, two radiologists evaluated each mediolateral oblique (MLO) view of 5 normal persons after mammographic examinations performed by 20 technologists. The breast positioning of a MLO view was assessed by an individual 3-point rating by each breast (pass, 2, intermediate, 1, and fail, 0) based on the following 6 criteria : (1) symmetry of the bilateral breasts, (2) the nipple profile, (3) visualization of the major pectoral muscle, (4) the presence of retroglandular fat, (5) inclusion of abdominal tissue with an elongated inframammary fold, and (6) the breast image without wrinkles. Thus the highest possible total rate was 24. The positioning assessment was carried out twice.<BR>Results : The positioning rating ranged from 16.2 to 22.0, with a mean of 19.6. At the first assessment, those technologists whose evaluation at a training course held by the Subcommittee for Imaging Unit Evaluation was A (2 technologists) and B-1 (2 technologists) gave positioning ratings of 20.8 and 20.3, respectively, while those whose evaluation was C (3 technologists) gave a rating of 18.5, the difference in rating between technologists A versus C and B-1 versus C being statistically significant (p = 0.011 and 0.035).<BR>Between the two assessments, 8 technologists attended a study course and another 10 did not. The former group of technologists increased their positioning rate from a mean of 20.1 at the first assessment to a mean of 20.6 (p = 0.105) at the second assessment, while the latter group did not show any improvement (from 19.5 to 19.5). The difference in rating between technologists who did and did not attend the study course was non-significant at the first assessement, but significant at the second assessment (p<0.01).<BR>These results imply that successive assessments of individual technologists in breast positioning would improve the overall quality of mammography at the institution.
