Intravoxel incoherent motion diffusion imaging of the liver: optimal b-value subsampling and impact on parameter precision and reproducibility
H Dyvorne, G Jajamovich, S Kakite, B Kuehn… - European journal of …, 2014 - Elsevier
Purpose To increase diffusion sampling efficiency in intravoxel incoherent motion (IVIM)
diffusion-weighted imaging (DWI) of the liver by reducing the number of diffusion weightings
(b-values). Materials and methods In this IRB approved HIPAA compliant prospective study,
53 subjects (M/F 38/15, mean age 52±13 y) underwent IVIM DWI at 1.5 T using 16 b-values
(0–800 s/mm 2), with 14 subjects having repeat exams to assess IVIM parameter
reproducibility. A biexponential diffusion model was used to quantify IVIM hepatic …
