Diffusion-weighted imaging and diffusion tensor imaging of asymptomatic lumbar disc herniation.
Diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) were performed on a healthy 31-year-old man with asymptomatic lumbar disc herniation. Although the left S1 nerve root was obviously entrapped by a herniated mass, neither DWI nor DTI showed any significant findings for the nerve root. Decreased apparent diffusion coefficient (ADC) values and increased fractional anisotropy (FA)...
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 کاملDiffusion-Weighted Imaging and Diffusion Tensor Imaging
Assessment of the integrity of the articular cartilage is considered key for the early diagnosis of osteoarthritis (OA). Diffusion-weighted imaging and diffusion tensor imaging have potential as biomarkers for cartilage composition and structure. The value of diffusion to detect compositional and structural changes in the cartilage matrix has been shown in ex vivo experiments for several years....
متن کاملDiffusion Weighted Imaging, Diffusion Tensor Imaging, and T2* Mapping of Lumbar Intervertebral Disc in Young Healthy Adults
BACKGROUND Although conventional magnetic resonance imaging (MRI) could provide excellent detection of morphological changes in the diagnosis of lumbar disc degeneration (LDD), it has some difficulties in discriminating minimal changes associated with early LDD before morphological or clinical alterations. Therefore, newer MRI techniques have emerged for investigation of early LDD. OBJECTIVES...
متن کاملWeighted Procrustes Analysis for Diffusion Tensor Imaging
There has been substantial interest in the development of methods for processing diffusion tensor fields, taking into account the non-Euclidean nature of the tensor space. In this paper, we generalise Procrustes analysis to weighted Procrustes analysis for diffusion tensor smoothing, interpolation, regularisation and segmentation in which an arbitrary number of tensors can be processed efficien...
