Magnetic susceptibility artifact is seen near structures with very high and low signal intensity (the sinus and brain tissue). Gradient echo sequences are known to demonstrate magnetic susceptibility artifact partly due to the lack of a 180° refocusing pulse.

The magnetic susceptibility of a material is a measure of whether an applied magnetic field creates a larger or smaller field within the material. MAGNETIC SUSCEPTIBILITY Magnetic susceptibility is the magnetic response of a substance to a magnetic field and can result in local magnetic field inhomogeneities and signal loss. These effects are proportional to field strength and the differences in susceptibility of two regions. Magnetic susceptibility increases with field strength.

When the magnetic susceptibility is measured in response to an AC magnetic field (i.e. a magnetic field that varies sinusoidally), this is called AC susceptibility. AC susceptibility (and the closely related "AC permeability") are complex number quantities, and various phenomena, such as resonance, can be seen in AC susceptibility that cannot occur in constant-field ( DC ) susceptibility. Magnetic susceptibility artifacts are more prominent with: A. Spin echo sequences B. Fast spin echo C. Inversion recovery D. Gradient echo.

Magnetic susceptibility artifact has been documented with various implants and devices, which require appropriate identification with screening of patients prior to subjecting them to magnetic resonance examination. PURPOSE: To determine whether magnetic susceptibility artifact on magnetic resonance (MR) images can be used to grade gliomas. 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.

Susceptibility describes theproperty ofmatter ofbecoming magnetized when exposed to a magnetic field. Paramag- The chemical shift artifact is proportional to the magnetic field strength (larger artifact on the middle image) and is inversely proportional to the receiver bandwidth (smaller artifact on the right image). Susceptibility artifact results from magnetic field inhomogeneities, and magnetic susceptibility is defined as the degree a substance can affect relative magnetic field strength as a fraction of the magnetic field in which it is contained.

Susceptibility artifacts occur as the result of microscopic gradients or variations in the magnetic field strength that occur near the interfaces of materials of different magnetic susceptibility. These artifacts are usually caused by metallic objects from previous surgical or interventional procedures near or in the imaging field of view, since the susceptibility of metal is much higher than
