For example, ferromagnetic materials are sub 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. Magnetic Susceptibility Artifact. Magnetic susceptibility is an inherent property of matter originating from its electron structure.

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. درباره ما.
