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-density-weighted MR imaging, and gradient-echo T2 Magnetic susceptibility artifacts (or just susceptibility artifacts) refer to a variety of MRI artifacts that share distortions or local signal change due to local magnetic field inhomogeneities from a variety of compounds. 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.

More results. Susceptibility definition · Susceptibility synonym · Susceptibility artifact The spurious echo artifact and susceptibility measurements a strong homogeneous magnetic field is often preferred, especially in clinical applications. Magnetic Resonance Imaging Magnetic Resonance in Neurology multiband sequence has helped reduce artifacts in areas of high susceptibility such as air Minimized susceptibility artifacts with SPACE.

Magnetic susceptibility artifacts (or just susceptibility artifacts) refer to a variety of MRI artifacts that share distortions or local signal change due to local magnetic field inhomogeneities from a variety of compounds. Susceptibility artifacts can also be reduced by increasing gradient strength for a given field-of-view and avoiding narrow bandwidth techniques. Thinner slices also help as do the use of parallel imaging techniques. The more severe metal artifacts may be reduced by specific metal artifact reduction pulse sequences (discussed in the next Q&A).

Magnetic Susceptibility Artifact. Magnetic susceptibility is an inherent property of matter originating from its electron structure. Once a substance is placed in an external magnetic field (B 0), a magnetic field is induced inside of it (M 0). Magnetic susceptibility (χ) is measured as the ratio of M 0 /B 0 and Magnetic susceptibility artifacts are prevalent on the boundary of air-containing paranasal sinuses, as well as bone-soft tissue interfaces in the spinal canal. The appearance of these artifacts on images from three different magnetic field strength instruments, 0.3, 0.5, and 1.5 Tesla were studied. Magnetic susceptibility of the elements and inorganic compounds. (Table from the Fermi National Accelerator Laboratory.
