"An Open-Source and Customizable Pseudo-Continuous Arterial Spin Labeling Sequence for Research Purposes"
Abstract: Arterial Spin Labeling (ASL) is an MRI technique that magnetically labels blood to quantify tissue perfusion, offering valuable insights into cerebrovascular, metabolic, and neurodegenerative conditions. Despite consensus efforts to standardize ASL methods, results can remain inconsistent across sites due to hardware differences and variations in sequence design. Existing post-processing tools and AI-based harmonization methods have improved comparability but still struggle with these technical discrepancies. To address this, we propose an open-source, fully customizable ASL sequence based on established consensus guidelines, designed for compatibility across multiple vendors. This approach aims to enhance data harmonization, accessibility, and reliability in multi-site ASL studies.

"Intrinsically Designed to Modulate Power: Understanding How a Muscle-Tendon Unit (MTU) Deals With Energy Input During Rapid Stretch"
Abstract: Muscle-tendon units (MTUs) can deal with a wide range of mechanical energy demands. This ability is, in part, owed to the interaction of the intrinsic properties between the muscle fascicles and the elastic elements within a given MTU. This talk will review insights gained from in situ stretch experiments aimed at unraveling the complex interaction between muscle fascicles and elastic elements to deal with power absorption demands using the turkey’s lateral gastrocnemius MTU as a model system.
