Fluid-sensitive
volumetric imaging of patients with metallic implants is potentially an
important diagnostic tool to assess for infection, implant loosening, or
other complications. Recent MR
techniques use spin echoes combined with additional encoding to substantially
reduce distortion and signal loss artifacts.
Here we demonstrate the use of these sequences with short TI inversion
recovery (STIR) to provide reliable fat suppression near metallic implants,
which is particularly important in assessment of many disorders.
