dc.description.abstractengThe scapholunate interosseous ligament plays a crucial role in maintaining wrist stability, and its dysfunction can lead to instability and progressive joint degeneration. This study investigates the use of real-time MRI to dynamically evaluate the scapholunate joint during wrist motion, aiming to assess its diagnostic utility and effectiveness in comparison to static imaging modalities. Ten healthy participants underwent real-time MRI scans during wrist abduction/adduction and fist-clenching maneuvers. Measurements were performed at proximal, medial, and distal landmarks on both dynamic and static images. Statistical analyses were conducted to assess the reliability of measurements at each landmark and to compare dynamic data with established static imaging results. Additionally, inter- and intraobserver variabilities were analyzed. Among the landmarks, medial measurements showed the highest concordance with static images and the lowest measurement variability. Distal measurements demonstrated a similar level of agreement but exhibited higher variability. Proximal measurements, however, showed significant deviations along with greater scatter. While no significant differences were found between abduction/adduction and fist-clenching maneuvers, notable inter- and intraobserver variabilities were observed across all measurement points. This study underscores the potential of real-time MRI for dynamic evaluation of the scapholunate joint, particularly at the medial landmark. Nevertheless, challenges such as variability in measurements persist. Future efforts focused on standardization and the integration of advanced image processing techniques could improve the precision and reliability of real-time MRI, promoting its adoption in clinical applications for dynamic wrist imaging.de
