Intravoxel incoherent motion (IVIM) diffusion-weighted imaging was performed using 12 b values: 0, 10, 20, 30, 40, 50, 80, 100, 200, 400, 800, and 1000 sec/mm2. To calculate IVIM parameters and apparent diffusion coefficient (ADC), 3 regions of interest (ROIs) were placed in the renal cortex and in the medulla, i.e., a total of 6 ROIs were used. Abbreviations: ADC = apparent diffusion coefficient, DWI = diffusion-weighted imaging, IVIM = intravoxel incoherent motion, MRI = magnetic resonance imaging, T2WI = T2-weighted imaging.

Intravoxel incoherent motion diffusion-weighted imaging

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. The requisites and challenges of quantitative evaluation beyond simple monoexponential relationships are highlighted. 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 . Both single-shot TSE-DWI and single-shot EPI-DWI were scanned twice respectively for 15 patients with lung cancer. 2018-06-28 · Purpose. IVIM-DW imaging has shown potential usefulness in the study of pancreatic lesions.

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.

Intravoxel incoherent motion imaging (IVIM) is a new magnetic resonance imaging (MRI) technique that can detect both diffusion and pseudo perfusion microscopic tissue information. Intravoxel incoherent motion (IVIM) imaging wasintroduced to assessbothtumor diffusion and perfusion noninvasively by analyzing the signal decay curve obtained from multiple b-value diffusion-weighted imaging (DWI) acquisition to separate the signal intensity arising from a vascular component and that from a nonvascular component [8]. ST REPORTS 163 DOI 1.13srep163 1 www.nature.comscientificreports Intravoxel Incoherent Motion Diffusion-weighted Magnetic Resonance Imaging for Monitoring the Early Response to ZD6474 Eighteen healthy volunteers underwent intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) scan of the liver twice in 1.5T MR scanner with signed informed consent approved by local ethic committees. A new method, called cardiac stationary phase based ECG trigger (CaspECG), and FB method were applied.
