Abstract: Highlights•A novel and efficient framework, MMR-Mamba, for multi-modal MRI reconstruction.•A Target modality-guided Cross Mamba (TCM) module for effective fusion in the spatial domain.•A Selective Frequency Fusion (SFF) module to integrate information in the frequency domain.•An Adaptive Spatial-Frequency Fusion (ASFF) module for spatial-frequency information fusion.•Extensive experiments on the BraTS and fastMRI knee datasets showcase superior performance.
