Intravoxel Incoherent Motion (IVIM) Imaging at Different Magnetic Field Strengths: What is Feasible?
, 2014 Due to limited SNR the cerebral applications of the intravoxel incoherent motion (IVIM) concept have been sparse. MRI hardware developments have resulted in improved SNR and this may justify a reassessment of IVIM imaging for non-invasive quantification ...

Application of intravoxel incoherent motion diffusion-weighted imaging in hepatocellular carcinoma
World Journal of Gastroenterology, 2022 The morbidity and mortality of hepatocellular carcinoma (HCC) rank 6th and 4th, respectively, among malignant tumors worldwide. Traditional diffusion-weighted imaging (DWI) uses the apparent diffusion coefficient (ADC) obtained by applying the monoexponential model to reflect water molecule diffusion in active tissue; however, the value of ADC is ...

Intravoxel Incoherent Motion (IVIM)
, 2020 Intravoxel incoherent motion (IVIM) can be seen as subfield of diffusion MRI. It allows tissue microcirculation (perfusion) to be investigated in addition to tissue microstructure (from molecular diffusion).
