Standardized regions of interest were defined in the femorotibial hyaline cartilage. Five DECT parameters were obtained: CT numbers in Hounsfield units (HU) at 80 and 140 kV, the electron density (Rho), the effective atomic number (Z\n                      <jats:sub>eff<\/jats:sub>\n                      ), and the dual-energy index (DEI).

Older age was associated with lower attenuations at 80 kV ( P &lt; 0.01) and 140 kV ( P &lt; 0.01), and with Rho ( P &lt; 0.01). OA was characterized by lower attenuation at 140 kV ( P = 0.03), but the lower Rho was nonsignificant after adjustment for confounders. In gout, hyaline cartilage exhibited lower Rho values (adjusted P = 0.04). Multivariable coefficients of association with Rho were \u22120.21 [\u22120.38;\u22120.04] ( P = 0.014) for age, \u22124.15 [\u22129.0;0.7] ( P = 0.093) for OA and 0.73 [\u22120.1;1.56] ( P = 0.085) for monosodium urate volume.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Gout was associated with DECT-detected changes in cartilage composition, similar to those observed in older patients, with some similarities and some differences to those seen in OA.
