In this chapter, the advantages and disadvantages of high magnetic fields for MRI are summarized and described. A review of the available literature is presented, and several imaging examples providing direct comparisons between field strengths are provided. The drive toward higher field strengths ...
Magnetic Susceptibility Effects in High Field MRI In high-magnetic-field MRI, both valuable image contrast and undesirable artifacts associated with the magnetic susceptibility effects are significantly increased. The magnetic field distortion in and by the human body is described with ... QX Yang,MB...
Is magnetic field strength a scalar? What causes a magnetic field? What is Earth's magnetic field made of? How strong is the magnetic field in an MRI? What kind of magnetic field is produced by a solenoid? Is gravity a magnetic field?
In subject area: Chemistry The Magnetic Hyperfine Field refers to the strength of the magnetic field experienced by a probe nucleus due to its surrounding magnetic moments, which can provide valuable information for position assignment and determining magnetic order in materials. It is highly sensitive...
