Breast cancer is one of the most common oncological diseases among women. Breast magnetic resonance imaging enables the assessment of breast tissue and lesions, with dynamic contrast-enhanced MRI being the core breast protocol. The aim of this master's thesis is to develop a software tool for automated breast tissue characterization. The proposed pipeline includes the registration of dynamic scans and the segmentation of the breast, fibroglandular tissue, blood vessels, and lesions. This was achieved by implementing existing tools and models as well as training custom models. The nnU-Net framework is utilized in this work for the segmentation of all breast structures. Particular focus was placed on the segmentation of fibroglandular tissue and vessels, where the available vessel ground-truth annotations were refined, an inference ablation study was performed, and custom models were trained. The individual steps and the achieved results are evaluated and discussed.

Student prezentoval výsledky své práce a komise byla seznámena s posudky. Doc. Šafránek položil otázku: Jaká je reprodukovatelnost softwaru? Jaké je state-of-the-art? V čem je vaše metoda přínosnější oproti publikovaným metodám? Prof. Provazník položila otázku: Co znamená pojem "složitější" případ, u kterého nebyly léze správně detekovány? Proč u tohoto subjektu model selhává? Student obhájil diplomovou práci a odpověděl na otázky členů komise a oponenta.
