Sažetak
Mortality reduction through screening mammography (SMG) is possible only with examination of high image quality (IQ), which should be performed with acceptable patient breast radiation dose (BRD). Besides film processing control, equipment assessment with breast phantom and dosimetry, periodical external mammographic IQ assessment (MIQA) is needed, including image labelling (L), breast positioning (BP), exposure (EX) and artefacts (AR) assessment. The nationwide breast cancer screening program (NBSP) has been introduced in Croatia in 2006, and the MIQA is initiated as the first step in establishing quality assurance/quality control (QA/QC) framework in breast imaging in Croatia. The current study was aimed: (1) to provide objective evidence about the technical MIQ in NBSP in Croatia, (2) to compare MIQ between different types of mammographic units (MUs), (3) to identify the common deficiencies, and (4) to propose corrective activities. Mammograms (MGs) for IQA were collected from a total of 84 MUs which participate in NBSP, which represents 70 % of all MUs nationwide: A total of 420 MG examinations were reviewed. Each MU was requested to submit ''what they consider to be their five best representative MGs, each one performed in one of five consecutive workdays''. Mean age of MG machines was 7.76 years (range 2 - 21), with no difference between four MU types. This very first study of MIQ in Croatia corroborated our intuitive impression of inadequate IQ, staff training and equipment in many MUs nationwide. As MIQ strongly influences BC detection rate, suboptimal QA/QC always carries a risk to compromise the success of NBSP. Deficiencies in SMG, especially in ID and BP reflect different level of competency of radiological staff in Croatia. Differences in MIQ in various MU types are determined by their organization, equipment, education, working habits and motivation. More efforts are needed to train both RTs and radiologists to implement and maintain QA/QC in their institutions.
