RAIDER: Rapid, anatomy-independent, deep learning-based PDFF and R2* estimation using magnitude-only signals
T. J. P. Bray, G. V. Minore, A. Bainbridge +4
There has been recent interest in the use of magnitude-based fitting methods for estimating proton density fat fraction (PDFF) and R2* from chemical shift-encoded MRI (CSE-MRI) dat…

Resolving quantitative MRI model degeneracy in self-supervised machine learning
Giulio V. Minore, Louis Dwyer-Hemmings, Timothy J. P. Bray +1
Quantitative MRI (qMRI) estimates tissue properties of interest from measured MRI signals. This process is conventionally achieved by model fitting, whose computational expense lim…
