Conventional silicone breast MR involves multi-contrast 2D scans. However, the use of 2D imaging risks the loss of fine structure visualization in the 3rd dimension. An isotropic 3D-FSE pulse sequence was first tested in a single-center study in 13 subjects with silicone breast implants (SBI). The images were evaluated by radiologists for quality and added utility of the bilateral, 3D scans. To allow for multi-site implementation of the 3D sequence, a bilateral breast phantom containing lipid, fibroglandular mimic and a silicone implant was tested across major MR vendors to ensure adequate signal-to-noise ratios and tissue contrast.
