“…The results demonstrated that the doses for the standard beast were satisfactory and in most cases within the reference levels of 2.5 mGy [2], when analyzed without taking into account the image quality. In particular, the presented results related to CR systems reflecting the necessity to establish procedures for optimisation that require the participation of a medical physicist, radiographers, radiologists and field engineers of both x-ray mammography equipment and CR system used as image receptors [10][11][12]. The physical measures expressing spatial resolution and signal-to-noise ratio are consistent with the published finding that sites employing CR systems had lower image quality [13].…”

Abstract. The purpose of this study is to investigate the radiation dose and technic in Serbia after two years of implementation of the breast screening programme. A total of 186 mammography units, including Full-Field Digital Mammography (FFDM), (SFM) units were used in the patient Dose (MGD), was assessed for the standard breast, while image quality was evaluated in terms of spatial resolution, threshold contrast visibility and Contrast to (1.8±0.94) mGy, (1.3±0.51) and (1.7±0.64) for CR, FFDM and SFM, respectively. Spatial resolution was better than lp/mm only for 3/186 (1.6%) units. In 34/186 (18%) units, spatial resolution was less tha contrast visibility was better than 1.2 in 41/186 (22%). initial implementation at the beginning of the population establish an effective system of regular and periodic mammograms with minimal possible radiation dose to population

“…Theoretically, the introduction of digital screening could have increased the CDR and thereby masked the lowering of CDR due to more restrictive recall strategy. However, this is unlikely as previous research has shown that digitalization in Flanders did not result in significantly different cancer detection rates [15]. Although the lowering of recall rate in combination with a stable CDR is a positive evolution, it is necessary to evaluate the negative counterpart i.e.…”

BackgroundWe examined 15 years of key performance indicators (KPIs) of the population-based mammography screening programme (PMSP) in Flanders, Belgium.MethodsIndividual screening data were linked to the national cancer registry to obtain oncological follow-up. We benchmarked crude KPI results against KPI-targets set by the European guidelines and KPI results of other national screening programmes. Temporal trends were examined by plotting age-standardised KPIs against the year of screening and estimating the Average Annual Percentage Change (AAPC).ResultsPMSP coverage increased significantly over the period of 15 years (+ 7.5% AAPC), but the increase fell to + 1.6% after invitation coverage was maximised. In 2016, PMSP coverage was at 50.0% and opportunistic coverage was at 14.1%, resulting in a total coverage by screening of 64.2%. The response to the invitations was 49.8% in 2016, without a trend. Recall rate decreased significantly (AAPC -1.5% & -5.0% in initial and subsequent regular screenings respectively) while cancer detection remained stable (AAPC 0.0%). The result was an increased positive predictive value (AAPC + 3.8%). Overall programme sensitivity was stable and was at 65.1% in 2014.In initial screens of 2015, the proportion of DCIS, tumours stage II+, and node negative invasive cancers was 18.2, 31.2, and 61.6% respectively. In subsequent regular screens of 2015, those proportions were 14.0, 24.8, and 65.4% respectively. Trends were not significant.ConclusionBesides a suboptimal attendance rate, most KPIs in the Flemish PMSP meet EU benchmark targets. Nonetheless, there are several priorities for further investigation such as a critical evaluation of strategies to increase screening participation, organising a biennial radiological review of interval cancers, analysing the effect that preceding opportunistic screening has on the KPI for initial screenings, and efforts to estimate the impact on breast cancer mortality.

“…The Flemish screening programme reported that the replacement of film-screen systems with DR systems lead to a 26% reduction in MGD for breasts simulated with 45-mm PMMA and a similar 26% reduction for the median MGD for patients. 14 Where film-screen systems were replaced with CR systems, Figure 5. Histograms of the average mean glandular dose to 50-60 mm-thick breasts for different types of imaging system.…”

Impact of the digitalisation of mammography on performance parameters and breast dose in the Flemish Breast Cancer Screening Programme

Abstract: • Performance parameters showed no major differences after digitalisation to CR or DR. • Transition from SFM to CR results in a higher mean glandular dose. • Transition from SFM to DR results in a lower mean glandular dose.
