Dec 21, 2015 Intravoxel incoherent motion and non-Gaussian diffusion MR imaging have the potential to give a semi-automatic diagnosis of lesions with high Aug 16, 2018 Therefore, the apparent diffusion coefficient (ADC) has become a widely accepted index to assess cellularity (14–19). Intravoxel incoherent Mar 28, 2017 Our purpose was to correlate different intravoxel incoherent motion (IVIM), histopathological and clinical parameters in rectal cancer.

At very low diffusion weighting the diffusion MRI signal is affected by intravoxel incoherent motion (IVIM) caused by dephasing of magnetization due to incoherent blood flow in capillaries or other sources of microcirculation. The aim of the study was to compare intravoxel incoherent motion diffusion-weighted imaging (DWI) for evaluating lung cancer using single-shot turbo spin-echo (TSE) and single-shot echo-planar imaging (EPI) in a 3T MR system. 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). REVIEW: Clinical Intravoxel Incoherent Motion and Diffusion MR Imaging Iima and Le Bihan and also contribute to the diffusion signal if diffusion-coupling terms (Dxy, Dxz) exist, which is the case when the tissue feature axes do not coincide with the gradient directions used for mea-surements. This mean ADC is then not rotationally invariant. Denis Le Bihan, father of modern diffusion imaging, coined the term intravoxel incoherent motion (IVIM) in the 1980s to refer to the microscopic translation of water molecules within a voxel during an MR experiment. When gradients are applied during evolution of the MR signal, IVIM causes spin dephasing and signal loss.

To address these issues, this paper develops an intravoxel incoherent motion- (IVIM-) MRI-based histogram analysis approach, which takes advantage of several hyperspectral techniques, such as the band expansion process (BEP), to expand a multispectral image to hyperspectral images and create an automatic target generation process (ATGP). Intravoxel incoherent motion imaging was performed on a 3 T magnetic resonance imaging scanner using 15 b values (0–800 s/mm 2) for 4 phantoms with different area fractions of the flowing water compartment (FWC%), at the infusion flow rates of 0, 1, 2, and 3 mL/min. Images were quantitatively analyzed using monoexponential free biexponential, and segmented biexponential fitting models. Objective To determine if intravoxel incoherent motion (IVIM) magnetic resonance perfusion can measure the quality of the collateral blood flow in the penumbra in hyperacute stroke.
