Abstract

Many different artefacts can occur during magnetic resonance imaging (MRI), some affecting the diagnostic quality, while others may be confused with pathology. An artefact is a feature appearing in an image that is not present in the original object. Artefacts can be classified as patient related, signal processing-dependent and hardware (machine)-related.This article presents an overview of MRI artefacts and possible rectifying methods.
