Susceptibility weighted magnetic resonance imaging

Abstract

Susceptibility-weighted imaging (SWI) is an important MRI modality for monitoring the progression of disease in the human brain. SWI is particularly sensitive to iron. Iron concentration holds great clinical interest in the progression of many neurological diseases as well as imaging blood. Challenges of these methods include long acquisition and reconstruction times as well as artificats due to bulk susceptibility variations such as air/tissue boundaries. The scans in this study use spiral trajectories, which are efficient but computationally demanding to reconstruct which has prevented spiral adoption in clinical applications.
