Balancing Accuracy and Precision: Optimal b-values for Diffusion Tensor Imaging Along the Perivascular Space
Both simulations and in vivo results suggest that the commonly used b-value of 1000 s/mm<sup>2</sup> is not optimal for assessing diffusion in the perivascular spaces. Intermediate b-values at approximately 700 s/mm<sup>2</sup> appear more suitable. However, further optimization of acquisition parameters is needed.
