The Contribution of MRI to the Mammographic Findings in Patients with Elevated Risk of Malignancy

Objective: We aimed to examine the contribution of breast magnetic resonance imaging (MRI) to mammography in high-risk patients with partial mastectomy, and/or with a family history. Material and Methods: 80 patients were scanned with mammography and MRI at our hospital. 30 of the patients had partial mastectomy due to the diagnosis of breast cancer. 52 patients had family history of breast cancer. Mammography scannings were performed under normal circumstances in standard craniocaudal (CC) and mediolateral (MLO) positions or in some special circumstances, scanings were performed using spot and magnification graphies. MRI scannings were performed using 1.5 Tesla MRI scanner with dual breast coil. Results: Fifty two of the patients enrolled in this study had a relative with breast cancer. 30 (37,5 %) out of 80 patients had history of breast cancer before. In 12 (15 %) out of 80 patients, the advantage of breast MRI to mammography could not be proven. In 54 (67,5 %) of the patients breast MRI had an advantage over mammography. In 5 (6,5 %) of the patients MRI had false negative results when compared with the pathology results. When compared with the pathology results in 9 (19 %) patients MRI scanning results were false positive. Conclusion: In this study, it was concluded that breast MRI scanning has reasonable advantage when compared to mammography for the patients who had breast cancer diagnosis or who has a first degree relative with breast cancer.
