  1. aConversion to unit mL/min/100 g may be performed by division with tissue density. According to Woodard et al. [41], tissue density is 1.05 g/cm3 for the skeletal muscle, 1.03 g/cm3 for the red marrow, 0.98 g/cm3 for the yellow marrow and 1.92 g/cm3 for the cortical bone
  2. bThe lesion contained sequester or developing sequester
  3. cCustom-drawn or elliptical VOI for irregular lesion; corresponding VOI in left limb was spherical
  4. dThe patella was necrotic and left out of the statistical analysis; see main text
