Breast MRI invasive cancer

The MRI reveals an invasive ductal cancer of the breast characterized as a dark mass on T2 (ringed by the circle) and as an enhancing mass on the post contrast T1-weighted images (arrow) in the axial (B and D) and sagittal projections (C). The spiculations emanating from the mass (arrowheads) and heterogeneous enhancement are well demonstrated. The signal void (dashed arrow) represents a clip placed at time of ultrasound-guided biopsy.
