Our proposed optimized diffusion-weighted imaging (DWI) can not only improve the image quality and spacial resolution, but also reduce chemical shift and susceptibility artifacts. In this study, we evaluated the utility of our proposed optimized DWI of liver magnetic resonance imaging. It can offer better diagnostic performance without reducing the signal-to-noise ratio of the normal liver parenchyma and lesion-to-non-lesion contrast-to-noise ratio with the conventional DWI which is widely used in the clinical practice. We suggest that our proposed optimized DWI should be advantageous for liver MRI to detect hepatocellular carcinoma.
