Quantitative dynamic contrast-enhanced parameters and intravoxel incoherent motion facilitate the prediction of TP53 status and risk stratification of early-stage endometrial carcinoma

Radiology and Oncology, 2023
The aim of the study was to investigate the value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and intravoxel incoherent motion (IVIM) in differentiating TP53-mutant from wild type, low-risk from non-low-risk early-stage endometrial ...

Functional mapping of the human visual cortex with intravoxel incoherent motion MRI.

PLoS ONE, 2015
Functional imaging with intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) is demonstrated. Images were acquired at 3 Tesla using a standard Stejskal-Tanner diffusion-weighted echo-planar imaging sequence with multiple b-values. Cerebro-

Intravoxel incoherent motion MRI in neurological and cerebrovascular diseases

NeuroImage: Clinical, 2018
Intravoxel Incoherent Motion (IVIM) is a recently rediscovered noninvasive magnetic resonance imaging (MRI) method based on diffusion-weighted imaging. It enables the separation of the intravoxel signal into diffusion due to Brownian motion and perfusion-

Variability of non-Gaussian diffusion MRI and intravoxel incoherent motion (IVIM) measurements in the breast. [PDF]

PLoS ONE, 2018
We prospectively examined the variability of non-Gaussian diffusion magnetic resonance imaging (MRI) and intravoxel incoherent motion (IVIM) measurements with different numbers of b-values and excitations in normal breast tissue and breast lesions ...

Incoherent-motion magnetic resonance imaging and pediatric Crohn disease

Archives of Clinical and Experimental Surgery, 2016
Crohn disease is a chronic inflammatory bowel disease of unknown etiology with approximately one-third of patients being children and adolescents. Long-standing inflammation can result in fibrostenosing disease, usually of the terminal ileum.

Simplified perfusion fraction from diffusion-weighted imaging in preoperative prediction of IDH1 mutation in WHO grade II–III gliomas: comparison with dynamic contrast-enhanced and intravoxel incoherent motion MRI

Radiology and Oncology, 2020
Effect of isocitr ate dehydrogenase 1 (IDH1) mutation in neovascularization might be linked with tissue perfusion in gliomas. At present, the need of injection of contrast agent and the increasing scanning time limit the application of perfusion ...
