1. Evaluation of silicona microstrip detectors as X-ray sensors in digital mammographyTadej Mali, Vladimir Cindro, Marko Mikuž, Urban Zdešar, Breda Jančar, 1999, original scientific article Abstract: Background. Position sensitive silicon microstrip detectors are used as sensors for X rays in a digital imaging system. Silicon detectors were used inan edgeon geometry, yielding high X ray detection efficiency. Material and methods. A small detector system was assembled and tested. Images of a standard, 5 cm thick phantom were made and evaluated. It is demonstrated, thatthe use of silicon detectors in mammography could significantly contributeto a reduction of dose. All images were made with skin entrance doses lower than 1 mGy. Results and conclusion. Microcalcifications with a diameter of 350microm could still be detected with skin entrance doses of about 0.25 mGy. It was demonstrated that a 5 Ip/mm pattern can be detected. Image processing should further improve the image quality.

3. Najpogostejše bolezni dojk in njihove mamografske značilnostiBreda Jančar, Igor Kocijančič, 2001, published scientific conference contribution Abstract: Radiološki inženir, ki se ukvarja z mamografsko diagnostiko, potrebuje osnovnoznanje o boleznih dojk. To je zlasti pomembno pri dodatnih slikovnih diagnostičnih postopkih, ki zahtevajo timski pristop. Zato so v sestavku na kratko opisane najpogostejše bolezni dojk s poudarkom na njihovih mamografskihznačilnostih.

4. Mamografske spremembe v dojkah po operativnih posegih in radioterapijiBreda Jančar, 1998, review article Abstract: Po končani terapiji primarnega karcinoma dojke s konzervirajočim kirurškim posegom in z radioterapijo, nastanejo v dojki spremembe, ki jih lahko zamenjamo z recidivnim ali annovo nastalim karcinomom. S poznavanjem pooperativnih in poobsevalnih sprememb, vidnih na mamogramih in s poznavanjem njihove časovne dinamike, ter uporabo vseh razpoložljivih mamografskih tehnik pa lahko z mamografijo zelo zgodaj odkrijemo recidiv. Če pravočasno zdravimo, s tem omogočimo dolgotrajno preživetje bolnic ali celo njihovo popolno ozdravitev.
