Abstract
Mammography is an effective and widely used method for breast diagnostics and early detection of breast cancer (screening). In order to obtain high quality mammograms at an acceptable breast dose, it is essential to use the correct equipment and perform regular quality control tests on mammography equipment. The aim of this work was to optimize radiation protection of patient and improve quality of mammography examinations by evaluating clinical image quality and measuring the entrance surface air-kerma for standard 4.5 cm breast thickness and the optical density of films herewith identifying problems and taking correction actions for optimization. The evaluation of mammography images of more than 180 patients was done according to selected image quality criteria and overall image quality assessment on a 5 point scale. The evaluation was performed in two hospitals. The results showed that up to 48% of cranio-caudal and 26% of medio-lateral oblique mammograms didn’t fulfill all quality criteria, but only about 4 % of images were unacceptable or of suboptimal quality. The repeated (after corrective actions) image quality evaluation revealed the improvement of image quality up to 30%. The entrance surface airkerma values were in range of 3.1-11.6 mGy and optical densities of films were in range of 1.11-1.86. The survey exhibited the potentiality to optimize radiation protection during mammography procedures by performing periodical image quality assessments and monitoring of doses.
