Validation of an MRi Technique for Measuring in-Vivo Glenoid Wear: A Tool for Understanding Glenohumeral Pain

Description

In a presentation from the ISTA 2024 conference held in Nashville, on behalf of Dr. Mahmood, the speaker Dr Ulrich Hansen discusses a proposed MRI technique to measure glenoid wear as an indicator of shoulder pain, particularly in patients undergoing ceramic hemiarthroplasty. Dr Hansen highlights the limitations of current diagnostic methods, such as joint space narrowing and CT scans due to high radiation exposure, and suggest using MRI as a safer alternative that can also assess rotator cuff status. He explains their comparative study involving micro CT and MRI scans, where they achieved promising results by enhancing MRI resolution. Measurements of glenoid wear demonstrated a maximum difference of only half a millimeter between the two imaging methods, with a promising average accuracy that would help surgeons monitor post-operative changes effectively. They caution that results are derived from cadaver tests, emphasizing the need for further validation in clinical settings due to potential patient movement during scans.
