Optimal acquisition scheme for flow‐compensated intravoxel incoherent motion diffusion‐weighted imaging in the abdomen: An accurate and precise clinically feasible protocol

Echo-planar imaging of intravoxel incoherent motion.

The recently established single-shot technique of echo-planar imaging of intravoxel incoherent motion (IVIM) for determining and imaging the variations of microscopic motions of water has been applied to studies of water perfusion in phantoms and to in vivo studies of diffusion and perfusion in cat and human brains. The phantom results demonstrate that perfusion levels comparable with those fou...

Intravoxel incoherent motion (IVIM) imaging at different field strengths – what is feasible ?

Introduction Since the introduction of the intravoxel incoherent motion (IVIM) concept by Le Bihan [1], the cerebral applications of this technique have been sparse due to the limited SNR. However, MRI hardware development in general and increased main magnetic field strength specifically, could result in improved SNR and may justify a reassessment of IVIM imaging for non-invasive quantificatio...

Intravoxel Incoherent Motion Imaging in Small Vessel Disease

Intravoxel incoherent motion imaging using steady-state free precession.

IVIM 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 x 8 min 32 s). A new method is proposed here, using steady-state free precession (SSFP), which allows IVIM images to be obtained in a c...

MR Imaging of Intravoxel Incoherent Motions

401 Molecular diffusion and microcirculation in the capillary network resuit in a distribution of phases in a single voxel in the presence of magnetic field gradients. This distribution produces a spin-echo attenuation. The authors have developed a magnetic resonance (MR) method to image such intravoxel incoherent motions (IVIMs) by using appropniate gradient pulses. Images were generated at 0....
