Distal femur cancellous bone mass and microarchitecture. Microcomputed tomography scans were performed on excised bone following exposure to 0.5 Gy 56Fe and/or 21 days of partial weightbearing at 1/6 g (G/6) (a, c, e) and following 21 days of recovery (b, d, f). a, b Percent bone volume per total volume (%BV/TV); c, d Trabecular thickness (Tb. Th); e, f Trabecular number (Tb. N). Sham-exposed animal means ± standard deviation are represented in black and Rad-exposed animal means ± standard deviation are represented in gray. Group means that share the same letter are not statistically different from one another (p < 0.05)
