Automated Motion Tracking of Vaginal Pessaries and Pelvic Floor Structures on Dynamic MRI
This pilot study demonstrates the feasibility of automated frame-by-frame motion to quantify pessary-pelvic floor interactions during physiologic loading. This proof-of-concept establishes a foundation for larger studies to explore patient- and device-specific determinants of pessary function and failure, with the ultimate goal of informing personalized device design and improving clinical outcomes.
