Diffusion-weighted imaging (DWI) can be used to evaluate the degree of tumor cell proliferation and tumor necrosis. The diffusion motion of water molecules is assumed to be Gaussian distribution, which has some limitations. In recent years, some advanced models have emerged that can provide more parameters to explore complex biological behaviors. Restricted spectral imaging (RSI) is one of them. However, the application of this model in liver disease is rare. The purpose of this study was to explore the potential value of the RSI model in the preoperative non-invasive differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC).
