Joseph Zerr answered my question, thank you!
The TI peaks for fat and silicone are close, but not identical. Water based STIR will still have signal in silicone. A separate silicone based STIR is used in breast imaging to help find free silicone. That sequence completely nulls the signal from silicone.
Hope that helps,
Joe

40 yr old male “injected his calved with liquid to make them bigger” 10 years ago. Now complains of bilateral calf pain.
These are images from an Open 1.2T MRI
I don’t understand the signal characteristics of the rounted foci …the largest in the subcutaneous soft tissues of the posteromedial calf.
Intermediate T1, Dark T1 and T2 fat sat, but Bright STIR.
There is no enhancement.
How can it be dark on T2FS and Bright on STIR?
