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. 001033896 536__ $$0G:(DE-HGF)POF4-5112$$a5112 - Cross-Domain Algorithms, Tools, Methods Labs (ATMLs) and Research Groups (POF4-511)$$cPOF4-511$$fPOF IV$$x0 001033896 7001_ $$0P:(DE-Juel1)199019$$aCao, Zhuo$$b1$$ufzj 001033896 7001_ $$0P:(DE-Juel1)188471$$aQuercia, Alessio$$b2$$ufzj 001033896 7001_ $$0P:(DE-Juel1)129394$$aScharr, Hanno$$b3$$ufzj 001033896 7001_ $$0P:(DE-Juel1)191494$$aPfaehler, Elisabeth$$b4$$ufzj 001033896 8564_ $$uhttps://juser.fz-juelich.de/record/1033896/files/MRI_Reconstruction_with_Regularized_3D_Diffusion_Model_R3DM.pdf$$yRestricted 001033896 909CO $$ooai:juser.fz-juelich.de:1033896$$pVDB 001033896 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)184644$$aForschungszentrum Jülich$$b0$$kFZJ 001033896 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)199019$$aForschungszentrum Jülich$$b1$$kFZJ 001033896 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)188471$$aForschungszentrum Jülich$$b2$$kFZJ 001033896 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129394$$aForschungszentrum Jülich$$b3$$kFZJ 001033896 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)191494$$aForschungszentrum Jülich$$b4$$kFZJ 001033896 9131_ $$0G:(DE-HGF)POF4-511$$1G:(DE-HGF)POF4-510$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5112$$aDE-HGF$$bKey Technologies$$lEngineering Digital Futures – Supercomputing, Data Management and Information Security for Knowledge and Action$$vEnabling Computational- & Data-Intensive Science and Engineering$$x0 001033896 9141_ $$y2025 001033896 920__ $$lyes 001033896 9201_ $$0I:(DE-Juel1)IAS-8-20210421$$kIAS-8$$lDatenanalyse und Maschinenlernen$$x0 001033896 980__ $$acontrib 001033896 980__ $$aVDB 001033896 980__ $$aI:(DE-Juel1)IAS-8-20210421 001033896 980__ $$aUNRESTRICTED
