The apparent diffusion coefficient (ADC) and IVIM parameters [tissue diffusion coefficient (D t), perfusion fraction (f p) and pseudodiffusion coefficient] were obtained from cancer and normal tissue using diffusion-weighted imaging with b-values of 0, 30, 70, 100, 150, 200, 300, 400, 500 and 800 s mm −2. Intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI), with a bi-exponential model, can not only observe the diffusion of tissue water molecules but also reflect the blood perfusion information of tissue microcirculation, compensating for the deficiencies of conventional DWI [15] . Intravoxel incoherent motion (IVIM) imaging is an advanced DWI technique that allows a separate quantitative evaluation of all the microscopic random motion that contributes to DWI, which is essentially represented by molecular diffusion and blood microcirculation (perfusion). 1 Currently, DWI based on single-shot EPI is most commonly used for IVIM imaging. 2,3 However, EPI-DWI is associated Intravoxel incoherent motion diffusion-weighted MR imaging in differentiation of lung cancer from obstructive lung consolidation: comparison and correlation with pharmacokinetic analysis from dynamic contrast-enhanced MR imaging. Eur Radiol 2014; 24: 1914 – 22 doi: 10.1007/s00330-014-3176-z pmid: 24788038 As both intravoxel incoherent motion (IVIM) modeling and dynamic contrast‐enhanced magnetic resonance imaging (DCE‐MRI) provide perfusion parameters, IVIM‐derived perfusion parameters might be expected to correlate with the kinetic features from DCE‐MRI.
