Diffusion magnetic resonance imaging (MRI) exploits the random motion of water molecules to probe the microstructural architecture of the living brain. By sensitising the MRI signal to molecular ...

While DW-SE is the leading diffusion MRI method, the sequence has several well-established limitations. These limitations often arise from its (1) long diffusion-encoding period and (2) EPI readout 2.

Patients with AAV and renal involvement had abnormal apparent diffusion coefficient, arterial spin labeling, T2*, and fractional anisotropy values on functional MRI compared with healthy controls.
