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 ...

Multi-centre reproducibility of diffusion MRI parameters for clinical sequences in the brain. [PDF]
, 2015 The purpose of this work was to assess the reproducibility of diffusion imaging, and in particular the apparent diffusion coefficient (ADC), intra-voxel incoherent motion (IVIM) parameters and diffusion tensor imaging (DTI) parameters, across multiple ...

Intravoxel incoherent motion modeling - Optimization of acquisition, analysis and tumor tissue characterization [PDF]
, 2018 Intravoxel incoherent motion (IVIM) analysis provides a means to obtain information on diffusion and perfusion from a single MRI sequence. The measurements are completely noninvasive and the results have been shown to be of interest, for example, in ...

Intravoxel incoherent motion: application in differentiation of hepatocellular carcinoma and focal nodular hyperplasia [PDF]
, 2017 PURPOSE:We aimed to explore whether intravoxel incoherent motion (IVIM)-related parameters of hepatocellular carcinoma (HCC) and focal nodular hyperplasia (FNH) demonstrate differences that could be used to differentiate and improve diagnostic efficiency.

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.
