FH, femoral head; PFD, proximal femoral diaphysis; DFD, distal femoral diaphysis; DFE, distal femoral epiphysis; PTE, proximal tibial epiphysis; PTD, proximal tibial diaphysis; MaxOut, maximum washout; Rout, washout rate; Tout, time of washout (min); n, number of joints used for analysis.
Negative values of FH indicate MR signal increase. Positive values of PFD, DFD, DFE, PTE, PTD and vertebra L3 indicate MR signal decrease.
