Synopsis

Keywords: Machine Learning/Artificial Intelligence, Elastography, Stiffness Maps

Motivation: AI has proven itself in improving MRI reconstructions, yet its potential in estimating MRE stiffness maps with rapidly acquired data remains unexplored.

Goal(s): Investigating the untapped potential of AI in MR Elastography, promising advancements in diagnostic accuracy and efficiency of this modality.

Approach: 3D FEM was used to create the dataset, and Deep Learning was used to reconstruct the stiffness maps from sparse wavefield data

Results: The Deep Learning model was able to effectively reconstruct the MRE-Stiffness maps at high acceleration rates. The model's performance was reported in terms of SSIM.

Impact: This innovative study leverages deep learning and finite element modeling to reconstruct liver stiffness maps from under-sampled MR Elastography data. The proposed AI approach demonstrates robustness and potential for accelerating stiffness estimation, paving the way for improved tissue stiffness estimation.
