MATERIALS AND METHODS: Twenty-nine patients with gliomas were prospectively examined with spin-echo T1-weighted MR imaging without and with contrast material enhancement, spin-echo or fast spin-echo T2- and proton Magnetic susceptibility artifact: Blooming low signal intensity (SI), often with high-signal partial halo Cement & bone graft material may be apparent on radiographs & CT Scar tissue also has low SI – Lacks magnetic susceptibility artifact – Follows surgical incision or located in operative bed • Foreign Body Susceptibility A magnetic susceptibility artifact is caused by the presence of an object in the FOV with a higher or lower magnetic susceptibility. The magnetic susceptibility of a material is a measure of whether an applied magnetic field creates a larger or smaller field within the material.
