Measure of magnetization transfer in multiple sclerosis demyelinating plaques, white matter ischemic lesions, and edema.
PURPOSE To define the percentage of magnetization transfer of multiple sclerosis (MS) plaques, ischemic white matter lesions, and vasogenic edema to determine whether this measurement can help differentiate these entities. METHODS Findings were compared in 25 patients with proved MS, 20 patients with white matter ischemic lesions, and 72 patients with white matter edema (caused by tumors, inf...
متن کاملA 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...
متن کاملNormal-appearing White Matter Quantitative Magnetization Transfer Imaging correlates with Disability in Multiple Sclerosis
Introduction Multiple sclerosis (MS) is an inflammatory disease of the central nervous system, whose neuroradiological hallmark are multifocal white matter (WM) lesions. Several pathological and MRI studies based on quantitative techniques have clearly demonstrated that diffuse abnormalities are present in the normal appearing WM (NAWM) and in lesions, and that they partially explain symptom se...
متن کاملDirty-appearing white matter in multiple sclerosis: volumetric MR imaging and magnetization transfer ratio histogram analysis.
BACKGROUND AND PURPOSE In contrast to "normal-appearing" white matter (NAWM) in patients with multiple sclerosis (MS), there are subtle, abnormal and diffuse signal intensity changes often seen on T2-weighted MR images, which we have referred to as "dirty-appearing" white matter (DAWM). These areas of DAWM have slightly higher signal intensity than that of NAWM, but lower than that of lesion pl...
متن کاملPathological 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...
