Uvod: DORA je preventivni državni presejalni program za zgodnje odkrivanje raka dojk. V program so povabljene vse ženske starostne skupine 50 – 69 let, ki prejmejo vabilo vsaki dve leti. Za zagotavljanje kakovosti mamografskih slik se 1 do 2-krat letno ocenjujejo mamogrami vseh DRI. V Sloveniji imamo svoj sistem za ocenjevanje, ki združuje merila PGMI in Dokustufen. Namen: Predstaviti najpogostejše napake, ki se pojavljajo pri CC in MLO projekcijah, kakšen je njihov delež in raziskati, ali se kakovost mamografskih slik zaradi kontrole kvalitete z leti izboljšuje. Metode dela: Zajemajo pregled literature in retrospektivno analizo podatkov. Zbrali smo podatke iz 4928 mamogramov, narejenih med leti 2011 in 2013. Za ocenjevanje smo uporabili PGMI lestvico. Rezultati in razprava: Ugotovili smo, da se je na slikah v MLO projekciji pojavilo za 22,08 % več napak kot na slikah v CC projekciji. Največ napak pri CC projekciji se je pojavilo pri nepravilnem prikazu prsne bradavice, kožne gube, PNL, pojav asimetrije in pojav neustreznega prikaza lateralnega parenhima. Pri MLO projekciji pa se je pojavilo največ napak pri prikazu inframamarne gube, kožne gube, neustrezni asimetriji in prikazu prsne bradavice. Prav tako smo ugotovili, da se je pri večini napak najpogosteje pojavijo napake 2. stopnje. Zaključek: Med leti 2011 in 2013 nismo zaznali večjega upada ali porasta pojavljanja napak, saj je Slovenija šele leta 2013 dobila svoj sistem in uvedla ločeno ocenjevanje projekcij ter bolje izobrazila kader.

Sekundarni naslov: Frequency of errors in mammographic images
Sekundarni povzetek: Introduction: Slovenian breast cancer screening programme, called DORA, is an organized popoulation based programme. It provides screening mammography every two years for all women in Slovenia aged 50 - 69 years old. In order to ensure the quality of mammograms in DORA programme, the mammograms of all radiographers are assessed once or twice a year. In Slovenia, we have our own evaluation system, which is a combination of PGMI criteria and Dokustufen. Purpose: To present the most common errors that occur in the CC and the MLO projections and also to investigate whether the quality control brings improvement of mammographic images. Methods: The methods of work comprise a literature review and the retrospective analysis. We collected data of 4928 mammograms that were made between 2011 and 2013. We used PGMI evaluation system. Results and discussion: We presented the results and comparisons in the tables and graphs for CC and MLO projections. We found that there were 22.08 % more errors on the MLO projections. The most common errors in the CC projection of both breasts were incorrect display of the nipple, skin folds, PNL, apperance of asymmetry and the apperance of inadequate display of the lateral parenchyma. The most common errors in the MLO projection of the both breasts were also skin fold, apperance of asymmetry and the incorrect display of the nipple. We also found that the most common erros were evaluated as level 2 errors. Conclusion: Between the years of 2011 and 2013, we did not notice any major increase or decrease of errors in mammograms. It is important to say, that Slovenia got its own evaluation system in the year of 2013 and also needed some time to educate all the radiographers working in screening programme DORA.
