(2015) Intravoxel incoherent motion diffusion-weighted MR imaging of the liver: effect of triggering methods on regional variability and measurement repeatability of quantitative parameters. Radiology 274:405–415. Article Google Scholar 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.

Published: 16 July 2020 2013-10-30 · Intravoxel incoherent motion (IVIM)–derived diffusion coefficient (D) involving diffusion-weighted MR imaging with multiple b values showed significantly higher accuracy in differentiating high- from low-grade hepatocellular carcinoma (HCC) than did the apparent diffusion coefficient (ADC) in receiver operating characteristic (ROC) analysis (area under the ROC curve = 0.838 and 0.728 for D and ADC, respectively; P = .026). Objectives: The diagnostic performance of intravoxel incoherent motion diffusion–weighted imaging (IVIM-DWI) in the differential diagnosis of breast tumors remains debatable among published studies. Therefore, this meta-analysis aimed to pool relevant evidence regarding the diagnostic performance of IVIM-DWI in the differential diagnosis of breast tumors.Methods: Studies on the differential Objective:To evaluate the intravoxel incoherent motion (IVIM) diffusion-weighted (DW) MRI for differentiating between benign and malignant musculoskeletal tumours at 3 T.Methods:65 patients with tr Intravoxel incoherent motion (IVIM)‐derived parameters in diffusion‐weighted MRI: Associations with prognostic factors in invasive ductal carcinoma.

Diffusion-weighted imaging (DWI), as a noninvasive functional imaging technique, has played an important role in lesion detection because of its high sensitivity to water molecular mobility. Besides, because of its shorter scanning time and lack of contrast medium, DWI has been widely applied in clinical practice,. Intravoxel Incoherent Motion Diffusion-Weighted MR Imaging for Characterization of Focal Pancreatic Lesions - PubMed IVIM-derived perfusion-related parameters could be helpful for the differentiation of common malignant tumors in the pancreas and for distinguishing malignant from benign IPMNs. Intravoxel incoherent motion diffusion-weighted MR imaging has value in characterizing the most common solid or cystic malignant tumors in the pancreas, owing to its ability to demonstrate not only Aim: To evaluate the feasibility of using intravoxel incoherent motion (IVIM) to measure diffusion and perfusion parameter variations in stroke. Materials and methods: Thirty-eight stroke patients were enrolled in the study.

to quantitatively assess all the microscopic translational motions that could contribute to the signal acquired with diffusion MRI. 2018-01-25 · Objective To evaluate intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) sequences for quantitative characterization of anal fistula activity.

Methods In this prospective study, DW-MRI and CT perfusion were conducted in nineteen patients with PDAC on the day before surgery. IVIM analysis of DW-MRI was performed and the Intravoxel incoherent motion (IVIM) MR imaging, initially developed by Le Bihan et al.
