Cine MRI can jointly obtain the continuous influence of the anatomical
structure and physiological and pathological mechanisms of organs in the two
dimensions of time domain and space domain. Compared with ordinary
two-dimensional static MRI images, the information in the time dimension of
cine MRI contains many important information. But the information in the
temporal dimension is not well utilized in past methods. To make full use of
spatiotemporal information and reduce the influence of artifacts, this paper
proposes a cine MRI reconstruction model based on second-order bidirectional
propagation, motion-guided deformable alignment, and efficient spatiotemporal
self-attention fusion. Compared to other advanced methods, our proposed method
achieved better image reconstruction quality in terms of peak signal-to-noise
ratio (PSNR) and structural similarity index (SSIM) metrics as well as visual
effects. The source code will be made available on
