The requisites and challenges of quantitative evaluation beyond simple monoexponential relationships are highlighted. 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.

Aim: To assess intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) for monitoring early efficacy of chemotherapy in a human gastric cancer mouse model. Methods: IVIM-DWI was performed with 12 b-values (0-800 s/mm(2)) in 25 human gastric cancer-bearing nude mice at baseline (day 0), and then they were randomly divided into control and 1-, 3-, 5- and 7-d treatment groups (n = 5 per group).

Epub 2013 Oct 28. Intravoxel incoherent motion diffusion-weighted MR imaging for characterization of focal pancreatic lesions. 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.

OBJECTIVE. The purpose of this study is to investigate whether the intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters are different between prostate cancer, benign prostatic hyperplasia (BPH), and healthy peripheral zone (PZ).

Intravoxel incoherent motion imaging (IVIM) is a new magnetic resonance imaging (MRI) technique that can detect both diffusion and pseudo perfusion microscopic tissue information.

to quantitatively assess all the microscopic translational motions that could contribute to the signal acquired with diffusion MRI. 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. 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. 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.
