Generative adversarial network (GAN)-saturation transfer (ST) architecture. (A) A conditional GAN framework, receives N raw, molecular information encoding semi-solid magnetization transfer/chemical exchange saturation transfer images, and is trained to simultaneously output the quantitative proton volume fraction and the exchange rate maps. (B) A fully connected neural network, receiving the full-length raw magnetic resonance fingerprinting image series (M > N) pixelwise, as well as T1, T2, and B0 maps, and yielding the reference proton volume fraction and exchange rate maps.34 The output of this network was used for training GAN-ST.
