57-year-old patient with breast biopsy clips who underwent breast MRI for high-risk screening. A. Axial T1-weighted non-fat-saturated MR image shows no area of signal void. No reader detected clip using this sequence. B. Axial contrast-enhanced in-phase Dixon image shows signal void in right breast (arrow), which corresponded with MammoMark/CorMark Bread Tie biopsy clip. All three readers detected clip on this sequence, with confidence scores of 4, 3, and 2; assessments all classified as true positives (i.e
