BACKGROUND AND PURPOSE: Despite a recent resurgence, intravoxel incoherent motion MRI faces practical challenges, including limited SNR and demanding acquisition and postprocessing requirements. A simplified approach using linear fitting of a subset of higher b-values has seen success in other organ systems. We sought to validate this method for evaluation of brain pathology by comparing Purpose . To combine Intravoxel Incoherent Motions (IVIM) imaging and diffusion kurtosis imaging (DKI) which can aid in the quantification of different biological inspirations including cellularity, vascularity, and microstructural heterogeneity to preoperatively grade rectal cancer.

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.

2014, 32(10). 1247-1258. 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.

Methods A 6 b values IVIM MRI sequence was acquired in stroke patients with large vessel occlusion imaged <16 hours of last seen well. IVIM perfusion measures were evaluated in regions of interest drawn in the BACKGROUND AND PURPOSE: IVIM MR imaging provides perfusion and diffusion information with a single diffusion-weighted MR image. We determined whether PP and D differ among various types of head and neck tumors. MATERIALS AND METHODS: The study cohort included 123 head and neck tumors: 30 SCCs, 28 benign and 20 malignant SG tumors, 36 lymphomas, and 9 schwannomas.

553 - 562 , 10.1002/mrm.24277 Intravoxel incoherent motion imaging has the possibility to detect liver abnormalities in young Fontan patients with good hemodynamics - Volume 29 Issue 7 - Kazuhiro Shiraga, Kojiro Ono, Ryo Inuzuka, Hiroko Asakai, Takumi Ookubo, Akira Shirayama, Kouji Higashi, Hiromichi Nakajima 2021-03-01 · Intravoxel incoherent motion (IVIM) imaging is based on diffusion-weighted imaging (DWI) MRI and can provide separate estimates for quantitative metrics of diffusion, representative of structural changes , and the perfusion fraction which is a measure related to microcirculation. Intravoxel incoherent motion (IVIM) magnetic resonance imaging is a potential noninvasive technique for the diagnosis of brain tumors. However, perfusion‐related parameter mapping is a persistent problem. The purpose of this paper is to investigate the IVIM parameter mapping of brain tumors using Bayesian fitting and low b‐values. Methods In this review, we discuss the principles of intravoxel incoherent motion as applied to body diffusion-weighted MRI. The evidence for the technique in measuring tissue perfusion is presented and the emerging clinical utility surveyed.
