Combination of temporal and spatial denoising methods for cine MRI

In this paper, we propose a denoising method for cine MRI acquired by MoPS. The MoPS-based cine MRI has a high FPS but contains reconstruction noise. DISPEL, a conventional method, performs denoising in the temporal domain. A neural network is further introduced to remove spatial noise. Different from most those methods requiring noisy and clean images, we choose an unsupervised scheme, N2N. We combine these two methods to perform temporal and spatial denoising for cine MRI. Experimental results show that the proposed method is able to remove noise from cine MRIs acquired by MoPS without removing tissue signal.
