Basic MRI Physics and Artifacts



In magnetic resonance imaging (MRI), strong magnetic fields are utilized to generate in vivo images reflecting specific chemical and physical properties of the tissue. Due to its diagnostic value, in combination with its non-invasive nature and the absence of ionizing radiation, MRI has become an important tool in modern health care. In this chapter, a brief introduction is given to the physics behind MRI, together with a description of common imaging and quantification techniques, as well as a summary of the most commonly occurring image artifacts.
