On the 29th of April 2025, the CIBM Breakfast & Science Seminar 50, was given by Martin Zach, fomr the CIBM SP EPFL Mathematical Imaging Section. The event was chaired by Frédéric Grouiller, Head, CIBM MRI HUG-UNIGE Clinical MR Imaging Section.
Establishing Trust in Data-Driven MRI Reconstruction
Abstract
Benchmarks in MRI reconstruction are dominated by data-driven methods, yet their clinical adoption remains limited due to trust issues. In this talk, we explore strategies to build confidence in these reconstructions by combining data-driven techniques with interpretable, model-based approaches rooted in MRI physics. We will highlight recent advances in algorithm design that integrate uncertainty quantification, allowing us to assess and communicate the reliability of the images. By merging the strengths of data-driven learning with the transparency of model-based methods, our approach enhances both image quality and diagnostic trust. This presentation will cover key developments, experimental insights, and the potential clinical impact of these techniques.
