Abstract: Highlights•We developed complementary 2D partial Fourier and circular-BUDA-EPI to achieve high-resolution diffusion MRI with reduced TE.•We utilized phase constrained low-rank reconstruction to account for phase variations and enable high-fidelity partial Fourier filling.•We demonstrated the effectiveness of our proposed method by producing high-fidelity diffusion MRI with 500 µm-isotropic resolution.
