Virtual Meetings

This virtual seminar will provide hands-on tutorials for acquisition- and reconstruction-based solutions for motion detection & correction. The seminar will cover:

• - Introductory talk on "Motion in MR"
• - Hands-on tutorial on Pulseq applications to acquisition & motion
• - Hands-on tutorial on BART applications to reconstruction & motion

This virtual meeting aims to introduce neuromodulation technologies with MR systems and their applications in psychiatric disorders.

In this presentation, Christof Karmonik, Ph.D., will discuss state-of-the-art magnetic resonance imaging techniques for vascular imaging, with an emphasis on cerebrovascular and aortic pathologies. The talk will cover high-resolution vessel wall imaging, 4D flow MRI, QISS for arterial and venous imaging, and ultra-high-field (7T) applications for visualizing vascular structures and pathologies with unparalleled detail. Dr. Karmonik will also present computational approaches, including fluid dynamics modeling and AI-driven image analysis, that enhance diagnostic interpretation and enable quantitative, patient-specific risk assessment. By integrating advanced imaging with machine learning and simulation, this multidisciplinary approach offers powerful insights into disease mechanisms and supports personalized clinical decision-making in vascular care.

Among other benefits, open science accelerates scientific discoveries, increases transparency, improves reproducibility, and enhances collaborations. Many funding organizations support reproducible research and open science, and there are now special programs and calls for proposals that explicitly aim to promote open science. This virtual meeting will provide insights into ongoing grant-funded MRI research projects where open science is a key outcome. Two speakers will introduce their projects, highlight the open science aspects, and share their experiences in obtaining grants for open science. Additionally, funding agency representatives will discuss the challenges encountered by bioimaging researchers, and thus why it is important to push for openness.

Significant efforts are underway to enhance the use of MR spectroscopy in clinical practice. This includes optimizing patient management workflows, integrating innovative tools such as artificial intelligence, and engaging in advanced statistical analysis. This virtual meeting will discuss the current clinical status of MR spectroscopy. Two speakers will present their projects and insights on MRS in clinical settings, aiming to improve patient management, advance data analysis on MRS, and incorporate MRS into daily patient care.

Hitting the target is the foremost aim of MRI-guided radiotherapy. But does one make sure that a target (most often a tumor) observed on an MRI scan is actually hit? For example, image warping due to gradient and static magnetic field imperfections will lead to geographical misses if those are not fully uncorrected for. Next, tumor motion, e.g. due to respiration, might lead to image blurring or other artifacts preventing accurate definition of the target volume if not taken into account.

The two lectures of this virtual meeting will dive into the origin of these errors and methods to quantify and correct them. Carri Glide-Hurst, Ph.D., DABR, FAAPM, will talk about the methods and phantoms she developed with her lab to benchmark MRI-guided radiotherapy workflows. Martin Fast, Ph.D., will present methods and recommendations for the safe clinical use of 4D-MRI. In the realm of radiotherapy, 4D-MRI is used to reduce image artifacts in case of respiratory motion and enables quantification of respiratory motion amplitudes.

This webinar is part of the ISMRM-WFPI Pediatric MRI webinar series, an ongoing collaboration between ISMRM and the World Federation of Pediatric Imaging. Together, these two organizations are uniting to improve quality in and access to pediatric MRI globally through knowledge dissemination and networking.

In this webinar, a journal club-style presentation and discussion will be led by the authors of the recent publication on the international standardization of pediatric MRI protocols. Our expert speakers and moderators will discuss the creation of the WFPI MR Protocols committee and discuss challenges & benefits of creating standardized protocols for pediatric MRI.

Diffusion MRI provides a window into tissue structure and function, with different diffusion times revealing distinct biological properties. This seminar will focus on how diffusion measurements at different time scales—microseconds, seconds, and months—can be used to study brain tissue.

The first talk will cover diffusion processes on the order of microseconds, where diffusion may be sensitive to micrometer-scale tissue features, such as cell sizes or diameters, and membrane permeability. The second talk will focus on diffusion changes over the scale of seconds, highlighting applications in functional imaging, including diffusion functional MRI. The final presentation will examine diffusion differences over months, with a focus on tracking long-term changes in connectivity using tractography.

This meeting will highlight new methods, findings, and challenges in time-dependent diffusion, providing an opportunity for discussion on how different time scales contribute to our understanding of tissue structure and function.
