CMMCSegNet: Cross-Modality Multicascade Indirect LGE Segmentation on Multimodal Cardiac MR

Figure 2

Different modalities of CMR imaging from the same patient (the two images are unpaired). LGE can enhance myocardial necrosis or scarring, which can evaluate effectively cardiac structure, cardiac function, myocardial perfusion, and myocardial activity, while bSSFP can highlight clearly the large blood vessels and coronary arteries because of more obvious contrast in the heart muscle and blood pool. To better adapt to cardiac structure segmentation, we will build a cross-modality translation network based on Cycle-GAN (Figure 1(b)).
