Comparison of Contrast-Enhanced Spectral Mammography and Contrast-Enhanced MRI in Screening Multifocal and Multicentric Lesions in Breast Cancer Patients

Figure 4

Imaging features of a 45-year-old woman with breast cancer in the right breast. (a) MLO position in the right breast. In CESM, the LE-MG imaging indicated dense breast parenchyma with no suspicious findings. (b) In CESM, the RSM imaging indicated the first mass with long spiculated edge, with significantly heterogeneous enhancement (wide arrow), which was diagnosed as BI-RADS 5. Under the right papilla, there was another small mass with significant enhancement and round margin (narrow arrow), which was diagnosed as BI-RADS 3. (c, d) T1WI image of CE-MRI fat compression in axial position: the morphology and location of the two lesions were consistent on both CESM and CE-MRI, which were diagnosed as BI-RADS 5 and 3, respectively. (e) US indicated only a hypoechoic mass with irregular edge (crosses), which was diagnosed as BI-RADS 4C. (f) It was confirmed that the first mass was an IDC, as revealed by HE staining under a magnification of 20×. The second mass was a small subcutaneous hemangioma.
