Advancing the intravoxel incoherent motion model as a tool for quantifying brain microvascular health
… blood flow is the intravoxel incoherent motion (IVIM) model of pseudodiffusive blood flow. In this work, a set of IVIM-derived microvascular biomarkers are pro- posed to quantify the mean microvascular blood velocity and mean microvessel length via diffusion weighted imaging (DWI). Very long …

Investigation of Microstructure of Uterine Fibroids in Magnetic Resonance guided High Intensity Focused Ultrasound Therapy
… (2) An intra-voxel incoherent motion (IVIM) based model is proposed in lieu of the current approaches to assess tissue microstructure (diffusion and perfusion) to distinguish treatable and non-treatable fibroids. It is found that with T2-correction, f (blood volume ratio in IVIM) is …

Quantitative Dwi As An Early Imaging Biomarker of The Response to Chemoradiation In Esophageal Cancer
… mono-exponential, intra-voxel incoherent motion (IVIM), and kurtosis. Summary measures of quantitative diffusion parameters were extracted from tumor voxels through volumetric contouring. These summary measures were retrospectively compared between histopathologically confirmed groupings of …

Functional Magnetic Resonance Imaging of Breast Cancer
… from the intra-voxel incoherent motion (IVIM) and diffusion tensor imaging (DTI) models. This work highlights a lack of standardisation in DWI protocols and methodology. Conventional acquisition techniques used in DWI often suffer from image artefacts and low spatial resolution. A …
