Abstract: 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.

Primer bolnice z invazivnim lobularnim karcinomom dojke in indikacije za preiskavo dojk z magnetno resonanco
Maja Marolt-Mušič, Kristijana Hertl, Marta Zebič, 2010, professional article

Abstract: Prikazujemo primer bolnice, ki je bila zaradi raka dojke obojestransko operirana. V drugem primeru je šlo za invazivni lobularni karcinom (ILC). Pri bolnici smo pred operacijo opravili preiskavo dojk z magnetno resonanco (MR), ki je pokazala večji obseg bolezni od pričakovanega. Pri bolnicah z ILC predoperativna preiskava z MR pri 28 % spremeni načrtovano operacijo. Preiskavo dojk z MR opravljamo tudi za odkrivanje karcinomov v predelih dojk, kjer mamografija in UZ sprememb ne pojasnita povsem, za odkrivanje primarnega tumorja ob pozitivnih pazdušnih bezgavkah, za oceno odgovora na kemoterapijo, za odkrivanje ruptur pri silikonskih vsadkih in za iskanje prostih silikonskih delcev ob rupturi. MR-preiskava dojk se uporablja tudi kot ena od presejalnih metod za odkrivanje raka dojk pri ženskah s povečanim tveganjem.
