Comparison of apparent diffusion coefficients and distributed diffusion coefficients in high-grade gliomas.
PURPOSE To compare apparent diffusion coefficients (ADCs) with distributed diffusion coefficients (DDCs) in high-grade gliomas. MATERIALS AND METHODS Twenty patients with high-grade gliomas prospectively underwent diffusion-weighted MRI. Traditional ADC maps were created using b-values of 0 and 1000 s/mm(2). In addition, DDC maps were created by applying the stretched-exponential model using ...
متن کاملApparent diffusion coefficients for differentiation of cerebellar tumors in children.
BACKGROUND AND PURPOSE Diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps provide information at MR imaging that may reflect cell attenuation and integrity. We hypothesized that cerebellar tumors in children can be differentiated by their ADC values. METHODS Brain MR imaging studies that included ADC maps were retrospectively reviewed in 32 patients with histologic...
متن کاملMulti-component apparent diffusion coefficients in human brain.
The signal decay with increasing b-factor at fixed echo time from brain tissue in vivo has been measured using a line scan Stejskal-Tanner spin echo diffusion approach in eight healthy adult volunteers. The use of a 175 ms echo time and maximum gradient strengths of 10 mT/m allowed 64 b-factors to be sampled, ranging from 5 to 6000 s/ mm2, a maximum some three times larger than that typically u...
متن کاملheterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
Interference of Inversion Recovery with Diffusion Weighted Imaging: Negative Apparent Diffusion Coefficients!
Introduction Diffusion weighted imaging (DWI) allows the determination of the apparent diffusion coefficient (ADC). Since several tissue compartments may be present in a voxel, e.g. tissue and cerebrospinal fluid [1] or tissue and blood [2], the measured ADC is an averaged value, weighted by these partial volumes. To reduce this partial volume effect, several investigators tried to null the mag...
