Keywords: Cartilage, Relaxometry, Repeatability, UTE-T2*This work examines the combined acquisition and segmentation repeatability of Cones UTE-T2* measures in tread mark cartilage regions and in small 2-D cartilage and meniscus ROIs in the knees of uninjured participants. Both intra- and inter-day repeatability assessments showed excellent average CVs of less than 10% in all tread mark ROIs and in all but 2 small 2-D ROIs segmented from only a single slice. ICC estimates were good to excellent (0.79–0.98) in all tread mark ROIs and ranged from moderate to excellent (0.54-0.98) in small 2-D ROIs corresponding to absolute precision errors of less than 1ms in most cases.
