Methods and Materials
Between March 2009 and December 2011 at the Dept.
of Diagnostic Imaging,
Institute of Oncology and Radiology of Serbia (IORS),
Belgrade,
Serbia the breast MRI examination was performed prior to biopsy in 53 patients with FCC,
with the 1.5-T system (Avanto, Siemens, Erlangen, Germany),
the standard bilateral breast coil,
and with the standardized breast MRI protocol.
In women with a palpable breast lesion,
core-needle biopsies were performed.
In women with a nonpalpable lesion,
second-look breast ultrasound and radioguided occult lesion localization (ROLL) were done prior to the surgical biopsy.
The histologic diagnoses were:
- nonproliferative lesions in 12 women (22.6%),
- proliferative lesions without atypia in 33 women (62.3%),
and
- proliferative lesions with atypia in eight (15.1%).
The MRI features were interpreted based on the terms proposed by the ACR BI-RADS lexicon [7].
ADC values were calculated for b=900 s/mm2 with the cut-off value of 1.2 x 10-3 mm2/s to distinguish malignant from benign lesions [8].
