A phantom for diffusion-weighted MRI (DW-MRI)

Can Dynamic Contrast-Enhanced MRI (DCE-MRI) and Diffusion-Weighted MRI (DW-MRI) Evaluate Inflammation Disease

The aim of the study was to investigate diagnosis efficacy of dynamic contrast-enhanced MRI (DCE-MRI) and diffusion-weighted MRI (DW-MRI) in Crohn's disease (CD). To find out the correlations between functional MRI parameters including K, Kep, Ve, Vp, and apparent diffusion coefficient (ADC) with a serologic biomarker. The relationships between pharmacokinetic parameters and ADC were also studi...

Accelerated Diffusion Operators for Enhancing DW-MRI

High angular resolution diffusion imaging (HARDI) is a MRI imaging technique that is able to better capture the intra-voxel diffusion pattern compared to its simpler predecessor diffusion tensor imaging (DTI). However, HARDI in general produces very noisy diffusion patterns due to the low SNR from the scanners at high b-values. Furthermore, it still exhibits limitations in areas where the diffu...

Novel anisotropic MRI diffusion phantom

Diffusion MRI (DMRI) comprises a growing list of methods, and with that the need for a reliable and robust MRI phantom with which one can calibrate and validate them. In this study we developed a novel anisotropic diffusion MRI phantom and demonstrated its applicability by producing fractional anisotropy (FA) maps derived from DTI and average pore diameter maps using double Pulsed Field Gradien...

Diffusion-Weighted (DW) Imaging in Ovarian Cystic Lesions: Value of DW Imaging Compared to T2-weighted Imaging at 3T MRI

Purpose : Only a few studies on diffusion weighted (DW) imaging of ovarian lesions have been reported (1-3). In previous studies, the role of DW imaging in distinguishing between benign and malignant cystic tumors may be limited. Katayama et al (3) reported that apparent diffusion coefficient (ADC) values may not provide additional information, especially to discriminate benign from malignant l...
