Anisotropy induced by macroscopic boundaries: surface-normal mapping using diffusion-weighted imaging.
In MRI, macroscopic boundaries lead to a diffusion-related increase in signal intensity near them--an effect commonly referred to as edge-enhancement. In diffusion-weighted imaging protocols where the signal attenuation due to diffusion results predominantly from the application of magnetic field gradients, edge-enhancement will depend on the orientation of these diffusion gradients. The result...
متن کاملAnisotropy Induced by Macroscopic Boundaries: Surface Normal Mapping Using DWI
INTRODUCTION Diffusion imaging has traditionally been used to infer information regarding tissue microstructure when the characteristic dimensions of the underlying geometry are smaller than the voxel size. However, the diffusion signal is sensitive to structures whose sizes are comparable to or greater than the voxels of the image. In this work, using a simple system of infinite parallel plane...
متن کاملdiffusion weighted imaging, diffusion tensor imaging, and t2* mapping of lumbar intervertebral disc in young healthy adults
conclusion adc, fa, and t2* values may quantitatively reflect the microstructural characteristics of np, therefore they could be used to detect the minimal changes of early ldd. results the adc, fa, and t2* values were different (p < 0.05) among different rois within the same disc or among corresponding rois in different level discs. while the average values of adc increased regularly with the ...
متن کاملcharacterization of soft tissue tumors by diffusion-weighted imaging
conclusion our preliminary results have shown that although there is some overlap between benign and malignant tumors, adding dwi, mr imaging to routine soft tissue tumor protocols may improve diagnostic accuracy. results there was only one patient with a malignant cystic tumor and was not included in the statistical analysis. the median adc values of benign and malignant tumors were 2.31 ± 1.2...
متن کاملComparison of quantitative T2 mapping and diffusion-weighted imaging in the normal and pathologic prostate.
In this study, diffusion-weighted images of the human prostate were successfully obtained, enabling quantification of apparent diffusion coefficients (ADCs) in normal and pathologic regions. A dual acquisition fast spin-echo sequence was used for accurate T2 calculation. T2 values were significantly higher in the peripheral zone than the central gland (P = 0.015). No significant correlations we...
