T2-weighted Imaging of Water, Fat and Silicone
We present a single, clinically feasible MRI sequence that provides robust T2-weighted imaging and water–fat–silicone separation for breast imaging with or without implants.
Using a 2D multi-echo FSE acquisition with incoherent ky–TE undersampling and joint compressed-sensing reconstruction, the method delivers high-resolution, artifact-free images across implant types, and enables accelerated imaging in 2.5 minutes, supporting a unified and efficient breast imaging protocols.

Comparison of three-plane reformats for water and silicone images from (a) the reference STIR two-echo 3D FSE and (b) the proposed multi-echo 2D FSE with joint WFS reconstruction. The proposed method generates artifact-free, co-registered, and high-resolution T2-weighted water, fat and silicone images in three planes.
