1. Outcome of MRI-guided vacuum-assisted breast biopsy - initial experience at Institute of Oncology Ljubljana, SloveniaMarta Zebič, Kristijana Hertl, Maksimiljan Kadivec, Miha Čavlek, Gašper Podobnik, Marko Snoj, 2012, izvirni znanstveni članek Povzetek: Background. Like all breast imaging modalities MRI has limited specificity and the positive predictive value for lesions detected by MRI alone ranges between 15 and 50%. MRI guided procedures (needle biopsy, presurgical localisation) are mandatory for suspicious findings visible only at MRI, with potential influence on therapeutic decision. The aim of this retrospective study was to evaluate our initial clinical experience with MRI-guided vacuum-assisted breast biopsy as an alternative to surgical excision and to investigate the outcome of MRI-guided breast biopsy as a function of the MRI features of the lesions. Patients and methods. In 14 women (median age 51 zears) with 14 MRI-detected lesions, MRI-guided vacuum-assisted breast biopsy was performed. We evaluated the MRI findings that led to biopsy and we investigated the core and postoperative histology results and follow-up data. Results. The biopsy was technically successful in 14 (93%) of 15 women. Of 14 biopsies in 14 women, core histology revealed 6 malignant (6/14, 43%), 6 benign (6/14, 43%) and 2 high-risk (2/14, 14%) lesions. Among the 6 cancer 3 were invasive and 3 were ductal carcinoma in situ (DCIS). The probability of malignancy in our experience was higher for non-mass lesion type and for washout and plateau kinetics. Conclusions. Our initial experience confirms that MRI-guided vacuum-assisted biopsy is fast, safe and accurate alternative to surgical biopsy for breast lesions detected at MRI only.

4. Mamografska tehnika - projekcije in kompresijaKristijana Hertl, Miljeva Rener, 1999, pregledni znanstveni članek Povzetek: Vsaka od različnih projekcij pri slikanju dojk doda svoj pomemben delež k prepoznavanju začetnega karcinoma dojke. Zelo pomembna je tudi pravilna in zadostna kompresija pri slikanju dojk. Nepravilno izvedena projekcija in kompresija lahko že ob prvem slikanju zavedeta radiologa k lažno negativnem izvidu, kar pa za ženo pomeni zakasnitev terapije in bistveno poslabša prognozo. Radiološki inženir in radiolog se morata zavedati, da z določeno projekcijo dobro prikažemo samo določene dele dojke. Pogoj za optimalen prikaztkiva dojke je prepoznavanje anatomskih odnosov med prsno steno, pektoralno mišico in žleznim tkivom.
