MaRBEL meeting 2025

Friday 7 Feb 2025, 08:30 → 18:20 Europe/Brussels

Academic Hall (Building A1 - University of Liège)

The field of MRI research continues to expand, bridging the realms of clinical applications and experimental research. With the rapid growth of methodologies like 7T MRI, the event will facilitate discussions on breakthroughs in imaging and analysis, shedding light on their potential to unlock new insights into complex biological structures and functions. This year's symposia and keynote lectures will cover a spectrum of specialized topics, including high-resolution knee imaging and in vivo and ex vivo histology of the brain as well as imaging the cortical layers, preclinical MRI applications, kidney imaging.

The inclusion of qualitative discussions, such as data archiving and BIDS data structuring further reflects the conference's commitment to a holistic understanding of MRI's role in research. Furthermore, a scientific sessions of a selection of submitted abstracts will give the opportunity to get more insights on MRI research in Belgium.

Like its predecessor, MARBEL 2025 will provide a space for MRI experts, technologists, and academics to engage in meaningful exchanges, share expertise, and collaboratively chart new directions for research. Through keynotes, breakout sessions, and networking opportunities, this conference aspires not only to enrich participants' technical knowledge but also to foster collaborations that transcend institutional boundaries, ultimately strengthening the MRI research community in Belgium and beyond. The conference is indeed open to any clinician, technician, logisitician and researcher working in Belgium as well as in any other countries.

11:00 → 12:00 Breakout session AM1. Closing the translational gap in renal functional MRI

This talk will focus on the steps necessary to bring (renal) functional imaging biomarkers to the clinic. Pim will guide the audience through the different steps, from discovery, validation, and implementation via clinical trials to clinical use. He will also discuss about the experience built up in COST Action PARENCHIMA, the ups and downs, and the importance of multidisciplinary collaboration.

Speaker: Prof. Pim Pullens (UGent)

11:00 → 12:00 Breakout session AM2. Mapping the layer-dependent organizationof the brain with in vivo MRI in humans

Recent advancements in MRI technology such as Ultra-High field (UHF) MRI at7 Teslas allow for unprecedented exploration of the brain’s mesoscalestructures. They offer insights into how sensory, perceptual, and cognitiveprocesses are implemented in cortical layers. This breakout session will explorethe importance of layer-specific research. It also showcases recent successes inusing layer-specific MRI research to study the visual cortex (its functionalorganization and its response to sensory deprivation). This breakout emphasizesthe promise of layer-specific MRI techniques in advancing knowledge of humanbrain organization and plasticity.

13:45 → 14:45 Breakout session PM2. The "My data organization is as good as yours" fallacy

In neuroimaging, scientists have been using open-source software since the mid-1990's but there existed no consensus on how researchers should systematically organize their data. Typically each lab would structure their dataset in their own way, such that only one/few researcher/s would know how to make sense of them. Moreover, the data could be spread across supports, e.g. in a lab book on a shelf, some Excel file on a laptop, and several hard-drives! Such lack of consensus leads to misunderstandings and time wasted on rearranging data or rewriting scripts expecting certain structure. In 2016, Gorgolewski et al. proposed the "Brain Imaging Data Structure" (BIDS): a framework to solve these issues in an practical and easy-to-adopt way, using open file formats. Since then, BIDS has been broadly adopted by the neuroimaging community and extended to describe several additional modalities and 'data derivatives'. BIDS success can be linked to its being a community effort, addressing clear use cases, solving common end-user problems, and presenting low technical barrier to entry. BIDS effectively provides a simple and intuitive way to organize and describe your neuroimaging/behavioural data. These principles could be extended to other fields.

16:15 → 17:05 Keynote: Mapping the Rusting Brain: Iron-SensitiveMRI Biomarkers for Neurodegeneration

Introduction by Mikhail Zubkov

Elevated brain iron levels are a hallmark of neurodegenerative diseases, includingAlzheimer’s and Parkinson’s. Although MRI provides a non-invasive means ofassessing brain iron using contrasts like quantitative susceptibility and transverserelaxation rates, these biomarkers often lack specificity. To address this, Evgeniya’swork integrated multiple iron-sensitive MRI parameters with biophysical models and3D quantitative histology to understand iron-induced contrast mechanisms. Thisapproach enables the development of cell-specific MRI biomarkers. For this talk,Evgeniya will discuss a key application of this work: mapping density and iron loadof dopaminergic neurons for the early detection of Parkinson's disease.
