Changes in cartilage morphology have shown to predict and monitor osteoarthritis progression with great sensitivity. However, the lack of a rapid and inexpensive MRI technique for imaging cartilage that can be implemented across vendors is a challenge in large multi-site clinical studies. In this work, we evaluate multi-vendor and scan-rescan reliability and explore left-right knee asymmetries of cartilage morphology measured using a rapid, 4-minute quantitative double-echo steady-state (qDESS) sequence. We demonstrate qDESS harmonization across vendors, which can produce high scan-rescan repeatability and high repeatability of left-right knee asymmetry of cartilage volume, surface area, and thickness metrics.
