چکیده

Purpose. Quantitative magnetization transfer imaging (qMTI) provides information on otherwise MR-invisible macromolecules via cross relaxation or proton exchange with water molecules. In cerebral white matter (WM), qMT parameters are assumed to be related to myelination and have been used as markers of WM pathology [1]. This is particularly true for the macromolecular pool-size fraction, M0b. In this abstract, we investigate whether high-resolution (200 μm isotropic ) qMTI at 3 T can visualize indicators of myelination well in a post-mortem marmoset brain. We compare our findings with T1 mapping in the same brain at 7 T, since T1-weighted imaging is more commonly used for visualizing neuroanatomy.

Magnetization transfer ratio may be a surrogate of spongiform change in human prion diseases.

Human prion diseases are fatal neurodegenerative disorders caused by misfolding of the prion protein. There are no useful biomarkers of disease progression. Cerebral cortex spongiform change, one of the classical pathological features of prion disease, resolves in prion-infected transgenic mice following prion protein gene knockout. We investigated the cross-sectional, longitudinal and post-mor...

A Novel Classification Method using Effective Neural Network and Quantitative Magnetization Transfer Imaging of Brain White Matter in Relapsing Remitting Multiple Sclerosis

Background: Quantitative Magnetization Transfer Imaging (QMTI) is often used to quantify the myelin content in multiple sclerosis (MS) lesions and normal appearing brain tissues. Also, automated classifiers such as artificial neural networks (ANNs) can significantly improve the identification and classification processes of MS clinical datasets.Objective: We classified patients with relapsing-r...

Pathological Assessment of Brain White Matter in Relapsing-Remitting MS Patients using Quantitative Magnetization Transfer Imaging

Introduction: Multiple sclerosis (MS) is characterized by lesions in the white matter (WM) of the central nervous system. Magnetic resonance imaging is the most specific and sensitive method for diagnosis of multiple sclerosis. However, the ability of conventional MRI to show histopathologic heterogeneity of MS lesions is insufficient. Quantitative magnetization transfer imaging (qMTI) is a rel...

The Assessment of Structural Changes in MS Plaques and Normal Appearing White Matter Using Quantitative Magnetization Transfer Imaging (MTI)

Introduction: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS), affecting mostly young people at a mean age of 30 years. Magnetic resonance imaging (MRI) is one of the most specific and sensitive methods in diagnosing and detecting the evolution of multiple sclerosis disease. But it does not have the ability to differentiate between distinct histopathologic...

Quantitative Magnetization Transfer Imaging of Human Cervical Spinal Cord at 3T

Introduction: The goal of this study was to determine the feasibility of performing quantitative magnetization transfer (qMT) at high resolution in the spinal cord on clinical 3T systems. While magnetization transfer (MT) imaging has been used to assess brain tissue microstructure, similar studies in the human spinal cord have been limited. This can largely be attributed to the difficulties ass...
