  Increasing the static magnetic field strength into the realm of ultrahigh
fields (7 T and higher) is the central trend in modern magnetic resonance (MR)
imaging. The use of ultrahigh fields in MR-imaging leads to numerous effects
some of them raising the image quality, some degrading, some previously
undetected in lower fields. This review aims to outline the main consequences
of introducing ultrahigh fields in MR-imaging, including new challenges and the
proposed solutions, as well as new scanning possibilities unattainable at lower
field strengths (below 7 T).
