abstract = {Magnetic Resonance Imaging (MRI) is a powerful imaging
technique widely used for visualizing structures within the
human body and in other fields such as plant sciences.
However, there is a demand to develop fast 3D-MRI
reconstruction algorithms to show the fine structure of
objects from under-sampled acquisition data, i.e., k-space
data. This emphasizes the need for efficient solutions that
can handle limited input while maintaining high-quality
imaging. In contrast to previous methods only using 2D, we
propose a 3D MRI reconstruction method that leverages a
regularized 3D diffusion model combined with optimization
method. By incorporating diffusion-based priors, our method
improves image quality, reduces noise, and enhances the
overall fidelity of 3D MRI reconstructions. We conduct
comprehensive experiments analysis on clinical and plant
science MRI datasets. To evaluate the algorithm
effectiveness for under-sampled k-space data, we also
demonstrate its reconstruction performance with several
undersampling patterns, as well as with in- and
out-ofdistribution pre-trained data. In experiments, we show
that our method improves upon tested competitors.},
