Figure 1From: Diffusion tensor imaging can detect the early stages of cartilage damage: a comparison studyRegion of interest (ROI) settings. The ROI was set in areas of arthroscopically confirmed cartilage damage, and the ADC, FA, and T2 were measured. The ROI was 55 voxels high and 40 voxels wide, and care was taken to measure all cartilage levels without including the subchondral bone.Back to article page
