A

rtifacts are artificial and potentially correctable changes in magnetic resonance images that negatively affect the quality of the study and are a potential source of diagnostic errors. Incorrect interpretation of artifact images, in addition to making an incorrect diagnosis and choosing the wrong treatment tactics, may require a repeat study, which entails a waste of time and effort of medical personnel and patients, ultimately leading to ineffective use of health care resources.

The purpose of this article is to consider the artifacts of magnetic resonance imaging, which are often found in practice and methods for their elimination or minimization.

In this review, by generalizing the experience of the authors and literary data, the most common and clinically significant artifacts of magnetic resonance imaging are presented, divided into large groups: motion artifacts, flow artifacts, chemical shift artifacts, magnetic susceptibility artifacts, artifacts associated with software and hardware. Their origin, manifestations, as well as methods for eliminating or minimizing are considered.

Magnetic resonance imaging artifacts have various causes and manifestations, by knowing it specialist in radiology can prevent their occurrence or minimize their impact on the study quality.

 

Keywords: magnetic resonance imaging, diagnostic errors, motion artifacts, flow artifacts, chemical shift artifacts, magnetic susceptibility artifacts.
