QIN DAWG Validation of Gradient Nonlinearity Bias Correction Workflow for Quantitative Diffusion-Weighted Imaging in Multicenter Trials
Previous research has shown that system-dependent gradient nonlinearity (GNL) introduces a significant spatial bias (nonuniformity) in apparent diffusion coefficient (ADC) maps. Here, the feasibility of centralized retrospective system-specific correction of GNL bias for quantitative diffusion-weighted imaging (DWI) in multisite clinical trials is demonstrated across diverse scanners independen...
متن کاملFunctional changes of apparent diffusion coefficient during visual stimulation investigated by diffusion-weighted gradient-echo fMRI
The signal source of apparent diffusion coefficient (ADC) changes induced by neural activity is not fully understood. To examine this issue, ADC-fMRI in response to a visual stimulus was obtained in isoflurane-anesthetized cats at 9.4 T. A gradient-echo technique was used for minimizing the coupling between diffusion and background field gradients, which was experimentally confirmed. In the sma...
متن کاملExploring the Possibility of Estimating Degree of Glioma Tumors by Measuring Apparent Diffusion Coefficient
Introduction: Most common glioma tumors are tumors of the central nervous system (CNS) which are the cause of about 40 to 50 percent of brain tumors. This type of cancer includes 2 to 3 percent of cancers in the world. Conventional MRI is powerless in the detection and differentiation of benign and malignant tumors. In this case, diffusion weighted imaging (DWI) can create cont...
متن کاملApparent diffusion coefficient of normal adrenal glands*
OBJECTIVE To assess the feasibility and reliability of apparent diffusion coefficient (ADC) measurements of normal adrenal glands. MATERIALS AND METHODS This was a retrospective study involving 32 healthy subjects, divided into two groups: prepubertal (PreP, n = 12), aged from 2 months to 12.5 years (4 males; 8 females); and postpubertal (PostP, n = 20), aged from 11.9 to 61 years (5 males; 1...
متن کاملApparent diffusion coefficient normalization of normal liver
Apparent diffusion coefficient (ADC) measurement in diffusion-weighted imaging (DWI) has been reported to be a helpful biomarker for detection and characterization of lesion. In view of the importance of ADC measurement reproducibility, the aim of this study was to probe the variability of the healthy hepatic ADC values measured at 3 MR scanners from different vendors and with different field s...
