Accelerated Radial Diffusion Spectrum Imaging using a Multi-Echo Stimulated Echo diffusion sequence

摘要

PurposeDiffusion Spectrum Imaging (DSI) provides us non-invasively and robustly with anatomical details of brain microstructure. To achieve sufficient angular resolution, DSI requires a large number of q-space samples, leading to long acquisition times. This need is mitigated here by combining the beneficial properties of Radial q-space sampling for DSI with a Multi-Echo Stimulated Echo Sequence (MESTIM).
