Overview

The main advantage of magnetic resonance imaging (MR) is the excellent tissue contrast, the possibility of the multiplanar imaging, non-invasiveness and not least the absence of the demonstrably harmful effect on the human body. Disadvantages consist in the fact that the examination of individuals with electronic implants and ferromagnetic vascular clamps is not possible, high purchase cost associated with high cost of screening, and limited availability of equipment in our country until recently [1]. In the present review the most important MR artifacts due to the patient are presented. The physical and technical aspects of the artifact origin and also the mechanism of its effect on the image signal is described.

Keywords:
artifacts, magnetic resonance, implants
