Abstract

Aim. The purpose of this study is to determine the clinical utility of an additional ultrasound examination in the evaluation of suspicious breast lesions detected initially on magnetic resonance imaging (MRI) in the
patients with invasive breast cancer. Patients and Methods. This retrospective study was conducted by analysing the radiology reports of 277 patients with breast cancer who underwent MRI as a part of the preoperative workup at the University Hospital Centre Zagreb, Department of Radiology. MRI scan detected new lesions were subsequently evaluated by ultrasound examination. Percutaneous biopsy or fine needle aspiration (FNA) was performed on suspicious lesions to obtain pathohistological or cytological confirmation. Correlation of MRI and ultrasound findings was compared with respect to the lesion type and size. Results. A total of 33 new lesions were detected on preoperative MRI. Ultrasound correlation was made in 25 lesions (75.8%). Ten lesions (40.0%) had benign characteristics. Fifteen lesions (60.0%) underwent biopsy or FNA. In total, nine lesions (36.0%) were
confirmed as malignant and 16 (64.0%) had benign characteristics. There was no recorded case of carcinoma in the group of lesions with benign appearance that were followed up for two years. Correlation rate of MRI and ultrasound findings was significantly higher in mass lesions (p<0.05). No correlation was found for foci. The size of other lesions did not affect correlation rate. Conclusion. Suspicious lesions detected on MRI can be successfully analysed on additional ultrasound examination. Correlation rate of MRI and ultrasound findings is high, with mass lesions exhibiting a higher percentage of correlation than non-mass lesions. The size of those lesions does not affect correlation rate. Additional ultrasound is useful in diagnostic workup of patients with MRI-detected breast lesion and can reduce the number of unnecessary biopsies.
