Diffusion-weighted Imaging of the Liver with Multiple b Values: Effect of Diffusion Gradient Polarity and Breathing Acquisition on Image Quality and Intravoxel Incoherent Motion Parameters—A Pilot Study
Hadrien A. Dyvorne,Nicola Galea,Thomas Nevers,M. Isabel Fiel,David L. Carpenter,Edmund Wong,Matthew R. Orton,Andre de Oliveira,Thorsten Feiweier,Marie-Louise Vachon,James S. Babb,Bachir Taouli +11 more
TL;DR: The RT BP DW imaging sequence had the best results in terms of image quality, reproducibility, and ability to discriminate between healthy and fibrotic liver with biexponential fitting.
Hepatocellular carcinoma: Short‐term reproducibility of apparent diffusion coefficient and intravoxel incoherent motion parameters at 3.0T
Suguru Kakite,Hadrien A. Dyvorne,Cecilia Besa,Nancy Cooper,Marcelo Facciuto,Claudia Donnerhack,Bachir Taouli +6 more
TL;DR: To evaluate short‐term test–retest and interobserver reproducibility of IVIM (intravoxel incoherent motion) diffusion parameters and ADC (apparent diffusion coefficient) of hepatocellular carcinoma (HCC) and liver parenchyma at 3.0T.

TL;DR: In this paper, the effect of different methods to convert MR signal intensity (SI) to gadolinium concentration ([Gd]) on estimation and reproducibility of model-free and modeled hepatic perfusion parameters measured with DCE-MRI was evaluated.
Intravoxel incoherent motion diffusion imaging of the liver: optimal b-value subsampling and impact on parameter precision and reproducibility.
TL;DR: A set of 4 optimized b-values can be used to estimate IVIM parameters in the liver with significantly shorter acquisition time with substantial degradation of IVIM parameter precision and reproducibility compared to the 16 b-value acquisition used as the reference.

Quantitative Liver MRI Combining Phase Contrast Imaging, Elastography, and DWI: Assessment of Reproducibility and Postprandial Effect at 3.0 T
TL;DR: Caloric intake had no/minimal/large impact on diffusion/stiffness/portal vein flow, respectively and differences in MR metrics before and after caloric intake and between healthy volunteers and liver disease patients were assessed.
