T1 STIR vs. T2 fatsat with orthopaedic hardware

Case contributed by Dr Tim Luijkx

Presentation

After open repair of peroneus tendons and arthrodesis of talcalcaneal joint.

Patient Data

Age: 50
Gender: Male

Illustration of the susceptibility for field inhomogeneities of spectral fat suppression sequences (e.g. SPIR, SPAIR, fatsat) as compared to inversion recovery sequences (e.g. STIR). Note both subcutaenous fat and the fat-containing bone marrow of the osseous structures.

SPAIR is much more affected by magnetic field inhomogeneities, such as caused by metal in this case. For this reason inversion recovery sequences may be preferred when orthopaedic hardware is present to achieve better fat suppression.
