Diffusion-weighted imaging (DWI) complements the more established T1, fluid-sensitive and
gadolinium-enhanced magnetic resonance pulse sequences used to assess several …

Magnetic resonance fingerprinting (MRF) is a promising framework that allows the
quantification of multiple magnetic resonance parameters with a single scan. MRF using fast …

Background Diffusion-weighted imaging (DWI) can depict the inflamed synovial membrane
