  1. Reference T2 values of the normal cartilage acquired with different techniques in different joints. As reported by Juras et al. [26], in addition to differences in cartilage structure and signal within the same anatomical district, T2 differences are present between different joints, reflecting the different structural composition (Source: Juras et al., Eur J Radiol 2016 - reference [26]). MESE Multi-echo spin-echo sequence, n.a. Not available, SD Standard deviation, TESS Triple-echo steady state
