For synthesis of a single target contrast within a multi-contrast MRI protocol, current approaches perform either one-to-one or many-to-one mapping. One-to-one methods take as input a single source contrast and learn representations sensitive to unique features of the given source. Meanwhile, many-to-one methods take as input multiple source contrasts and learn joint representations sensitive to shared features across sources. For enhanced synthesis, we propose a novel multi-stream generative adversarial network model that adaptively integrates information across the sources via multiple one-to-one streams and a many-to-one stream. Demonstrations on neuroimaging datasets indicate superior performance of the proposed method against state-of-the-art methods.
