•Monte Carlo simulations of diffusion MRI suggest a simple metric of axon diameter-the change in the radial apparent diffusion coefficient estimated at different diffusion times, ΔD⊥.•ΔD⊥ increased with effective mean axon diameter, and was relatively independent of extra-axonal volume fraction, g-ratio, myelin water exchange, and the free diffusion coefficient of water.•The slope of ΔD⊥ increased with the difference in effective diffusion time of the diffusion encoding waveforms.•Both extra- and intra-axonal water can contribute to ΔD⊥, providing sensitivity to small and large axon diameters, respectively. |
