Keywords: Low-Field MRI, MR FingerprintingMagnetic susceptibility changes at interfaces induce artefacts, and hence compromises MRI diagnostic value. Low-Field (LF) MRI is inherently less sensitive to susceptibility artifacts making it suitable for imaging near metallic implants. In addition, the dispersion in T1-contrast is enhanced at LF. To evaluate the potential for new contrast mechanisms, quantitative imaging would be key if acquisition times are compatible with clinical constraints. In that context, model-based multi-parametric OPTIMUM was performed in a healthy volunteer’s forearm carrying a titanium plate from plate-osteosynthesis surgery. Performance of two signal models, one oblivious to intravoxel dephasing and the other accounting for it was compared.
