Intravoxel incoherent motion perfusion imaging in acute stroke: initial clinical experience [PDF]

Neuroradiology, 2014
Intravoxel incoherent motion (IVIM) imaging is an MRI perfusion technique that uses a diffusion-weighted sequence with multiple b values and a bi-compartmental signal model to measure the so-called pseudo-diffusion of blood caused by its passage through the microvascular network.

Intravoxel incoherent motion imaging using steady‐state free precession

Magnetic Resonance in Medicine, 1988
AbstractIVIM MR imaging is a method which generates images of diffusion and perfusion in vivo. Until now, intravoxel incoherent motion (IVIM) images have been obtained using spin‐echo sequences with extragradient pulses, resulting in long acquisition times (typically 2 × 8 min 32 s).

Intravoxel Incoherent Motion Imaging in Small Vessel Disease

Stroke, 2017
Background and Purpose-Cerebral small vessel disease (SVD) is associated with cognitive impairment. This may be because of decreased microstructural integrity and microvascular perfusion, but data on these relationships are scarce.

SpinDoctor-IVIM: A virtual imaging framework for intravoxel incoherent motion MRI [PDF]

Medical Image Analysis
Intravoxel incoherent motion (IVIM) imaging is increasingly recognised as an important tool in clinical MRI, where tissue perfusion and diffusion information can aid disease diagnosis, monitoring of patient recovery, and treatment outcome assessment.

Intravoxel Incoherent Motion MR Imaging of the Kidney: Pilot Study

, 2012
MR examinations (Achieva 3 T, Philips, Best, The Netherlands) were performed at five different occasions in a healthy volunteer (male 60 years) and in one renal cancer patient (male 78 years) with normal renal function (creatinine 88 μmol/L). Intravoxel incoherent motion (IVIM) coefficients D + D* were measured using respiratory-triggered diffusion ...

Detection of synovial inflammation in the sacroiliac joint space through intravoxel incoherent motion imaging: an alternative to contrast agents. [PDF]

Diagn Interv Radiol
PURPOSE: We investigated the diagnostic accuracy of simplified intravoxel incoherent motion (IVIM) imaging for detecting synovial inflammation in the sacroiliac joint (SIJ) in a population with active sacroiliitis.

Implicit Modeling With Uncertainty Estimation For Intravoxel Incoherent Motion Imaging [PDF]

2019 IEEE 16th International Symposium on Biomedical Imaging (ISBI 2019), 2019
Intravoxel incoherent motion (IVIM) imaging allows contrast-agent free in vivo perfusion quantification with magnetic resonance imaging (MRI). However, its use is limited by typically low accuracy due to low signal-to-noise ratio (SNR) at large gradient encoding magnitudes as well as dephasing artefacts caused by subject motion, which is particularly ...

Fetal MRI: what’s new? A short review

European Radiology Experimental, 2023
Fetal magnetic resonance imaging (fetal MRI) is usually performed as a second-level examination following routine ultrasound examination, generally exploiting morphological and diffusion MRI sequences.

Interobserver Reliability on Intravoxel Incoherent Motion Imaging in Patients with Acute Ischemic Stroke. [PDF]

AJNR Am J Neuroradiol, 2022
Noninvasive perfusion-weighted imaging with short scanning time could be advantageous in order to determine presumed penumbral regions and subsequent treatment strategy for acute ischemic stroke (AIS). Our aim was to evaluate interobserver agreement and the clinical utility of intravoxel incoherent motion MR imaging in patients with acute ischemic ...
