Keywords: Contrast mechanisms: Susceptibility, Physics & Engineering: Low-field MRI
The magnetic susceptibility effects are generally characterized by geometric distortion, very dark and very bright contrast areas. In this talk, the pros and cons of the susceptibility effects at low field are introduced. Several examples of susceptibility-weighted imaging at low field show the contrast features and their clinical challenges. Opportunities of high sensitivity in-vivo contrast agents for low field MRI are discussed. More importantly, the advantages and opportunities of lower sensitivity to susceptibility effects at low field strengths are highlighted, particularly in applications such as imaging implants and lung tissue.
