Diffusion kinetics of CA4+ in mouse articular cartilage quantified by serially immersing mouse femurs (n = 5) in CA4+ and scanning at the following time points 0, 5, 10, 20, 30, 60, 90 and 240 minutes. Data were fit to an exponential mode and the time constant tau was found to be 6.3 minutes. $\mu CT \mathit{Attenuation}= (1-0.225\times e^{\frac{\mathit{tau}}{6.3}})\times 0.977$
