results when the two ms groups were compared together, we found that cr was significantly increased (p value=0.008) and naa/cr was significantly decreased (p value=0.03) in non-enhancing lesions in ppms compared with rrms. there was no significant difference in naa, cho or naa/cho between the two ms subtypes. conclusion mrs is a potential way to differentiate ppms and rrms. objectives we compar...

     Multiple sclerosis (MS) is an inflammatory, demyelinating, neurodegenerative disorder of the central nervous system (CNS) of unknown etiology. Isolated oculomotor nerve palsy is found rarely in children with MS. We present a case of MS in 10-year-old boy, who had bilateral ptosis associated with medial gaze restriction. The extraocular muscle examination demonstrated bilateral adduction pa...

background: back pain is a common patients’ complaint, and its etiology is important because of different potential treatment approaches (based on causes). for a better diagnosis, magnetic resonance imaging (mri) is widely used in clinical settings that may result in inappropriate requests. this study aims to evaluate the appropriateness of the lumbosacral mri requests in patients with back pai...

purpose this study was performed to introduce and evaluate the potential of kinematic magnetic resonance imaging (kmri) using a high-field open-magnet magnetic resonance (mr) system. methods we attempted to perform kmri of healthy volunteers’ lumbar spine and knee in the lateral position and ankle in the supine position utilizing the superconducting, horizontally opened, 1.2 t mr system (oasis,...

In the late ‘80s magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) revolutionized the care and monitoring of patients with multiple sclerosis (MS). For the first time detailed, high resolution images of the brain, spinal cord and lesions could be made by MRI in vivo, and followed over time. However, the changes detectable on T1or T2-weighted magnetic resonance images ar...

BACKGROUND Beta(2) adrenoreceptor expression on peripheral blood mononuclear cells is increased in progressive multiple sclerosis. This increase has been correlated with disease activity in relapsing-remitting multiple sclerosis. OBJECTIVE To determine the beta(2) adrenoreceptor expression in primary and secondary progressive multiple sclerosis in relation to findings on magnetic resonance im...

Diffusion Tensor Magnetic Resonance Imaging (DT-MRI): Method and Application Lan Lin Abstract Diffusion tensor magnetic resonance imaging (DT-MRI) is a recently developed MRI technique that provides the quantitative information about the integrity and orientation of the random motion of hydrogen atoms within water molecules in all three dimensions. It is a unique method of assessing the importa...

Magnetic resonance imaging (MRI) plays a vital role in the scientific investigation and clinical management of multiple sclerosis. Analyses of binary multiple sclerosis lesion maps are typically "mass univariate" and conducted with standard linear models that are ill suited to the binary nature of the data and ignore the spatial dependence between nearby voxels (volume elements). Smoothing the ...
