Water-Specific Quantitative MRI Relaxometry of the Brain using Spatial-Spectral Water Excitation: Preliminary Experience
Methods: The mixed turbo spin echo pulse (mixed-TSE) sequence was implemented with second order binomial water-selective spatial-spectral excitation pulses (1), hereafter SSE-mixed-TSE (Figure 1). Mixed-TSE is a four time point pulse sequence that incorporates the principles of differential T1and T2-weighting in a single acquisition. By substituting the standard spatially-selective excitation p...
متن کاملQuantitative properties (water content, relaxometry, MT) of the post mortem brain: a baseline for normal tissue
Target Audience Scientists using MRI of fixed tissue. Purpose: MRI of fixed tissue is an excellent way to study pathological changes caused by different diseases with great anatomical detail. It is, however, known that properties of tissue change with fixation. The aim of this study was to investigate post mortem formalin-fixed brains quantitatively in order to provide a baseline for MR paramet...
متن کاملSynthetic quantitative MRI through relaxometry modelling
Quantitative MRI (qMRI) provides standardized measures of specific physical parameters that are sensitive to the underlying tissue microstructure and are a first step towards achieving maps of biologically relevant metrics through in vivo histology using MRI. Recently proposed models have described the interdependence of qMRI parameters. Combining such models with the concept of image synthesis...
متن کاملT1 relaxometry of crossing fibres in the human brain
A comprehensive tract-based characterisation of white matter should include the ability to quantify myelin and axonal attributes irrespective of the complexity of fibre organisation within the voxel. Recently, a new experimental framework that combines inversion recovery and diffusion MRI, called inversion recovery diffusion tensor imaging (IR-DTI), was introduced and applied in an animal study...
متن کاملQuantitative assessment of brain iron by R(2)* relaxometry in patients with clinically isolated syndrome and relapsing-remitting multiple sclerosis.
BACKGROUND Increased iron deposition has been implicated in the pathophysiology of multiple sclerosis (MS), based on visual analysis of signal reduction on T(2)-weighted images. R(2)* relaxometry allows to assess brain iron accumulation quantitatively. OBJECTIVE To investigate regional brain iron deposition in patients with a clinically isolated syndrome (CIS) or relapsing-remitting MS (RRMS)...
