New framework synthesizes multi-shell dMRI from single-shell data

By PulseAugur Editorial · [1 sources] ·

Researchers have developed DTI-SHNet, a novel framework designed to synthesize multi-shell diffusion MRI (dMRI) data from single-shell inputs. This method operates in the spherical harmonics (SH) coefficient domain and utilizes diffusion tensor imaging (DTI) as a prior to guide a 3D U-Net regressor. The framework incorporates a signal consistency regularization to ensure accuracy in both coefficients and signal fidelity. Experiments on UK Biobank and Cam-CAN data demonstrate that DTI-SHNet produces competitive visual quality and better preserves downstream diffusion measures compared to existing methods. AI

    DTI-Guided Volumetric Spherical Harmonics Regression for Single-to-Multi-Shell dMRI Synthesis

    arXiv:2609.14312v1 Announce Type: new Abstract: Multi-shell diffusion MRI (dMRI) unlocks more expressive microstructural modeling than single-shell scans, yet its longer acquisition time hinders deployment in large-scale cohorts and time-constrained clinical settings. Synthesizin…
