Abstract
Introduction Digital mammography aims to clinically detect breast pathology or cancer. This is important as breast cancer has one of the highest incident and mortality rates worldwide for women. The aim of this study was to evaluate several imaging and demographic parameters of the 2D imaging done at Universitas Academic Hospital and to compare the mean glandular dose (MGD) values obtained to recent studies published from other institutions worldwide. Materials and methods Data were collected for 200 patients who underwent mammographic imaging at Universitas Academic Hospital. The data were analysed for the patient age, MGD, mAs, kV, target filter combination, compression force and compressed thickness from the Digital Imaging and Communications in Medicine file. Results Imaging parameter results showed that the average MGD was 1.52 ± 0.71 mGy, the average compression force, 69 N, the average kV, 30, the average mAs, 138 and the average compressed thickness, 58 mm. The mean patient age was recorded as 55 years. Conclusion The MGD from Universitas Academic Hospital compared well with the average screening MGD values of other institutions worldwide (average 1.72 ± 0.36 mGy). Higher MGD values were expected for Universitas Academic Hospital as diagnostic mammography and not screening mammography is practiced at Universitas Academic Hospital. The mean compression force is considered low if compared to the recommendations from the European guidelines of a minimum of 110 N compression force. The performance of the Fully Automated Self adjusting Tilt compression mode could explain lower registered compression values found in this study.
