20.500.12556/DiRROS-18496 Outcome of MRI-guided vacuum-assisted breast biopsy - initial experience at Institute of Oncology Ljubljana, Slovenia 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. dojke rak (medicina) MRI biopsija true false true Association of Radiology and Oncology Ljubljana Angleški jezik Slovenski jezik by Authors Neznano 2024-03-21 08:15:54 2024-03-21 08:15:54 2024-03-22 03:48:31 0000-00-00 00:00:00 2012 0 0 Soavtorji: Kristijan Hertl, Maksimilijan Kadivec, Mihael Čavlek, Gašper Podobnik, Marko Snoj; str. 97-105, I no. 2 Vol. 46 Jun. 2012 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2012-06-01 618.19-006.6-076 1318-2099 10.2478/v10019-012-0016-0 1311099 RAZ_Zebic_Marta_2012.pdf RAZ_Zebic_Marta_2012.pdf 1 6C8AD01FCC374E2B331F9CA2F3E76972 cf109c6e2db45bac3983af4045640e17302746530a5a4d94c382c753f382e2c5 605cc281-e753-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25204 Onkološki inštitut Ljubljana 0 0 0
