چکیده
Background: We clinically evaluated the quality of white matter lesions (WML) cerebrum on 3D inversion recovery ultrashort echo time (IR-UTE) magnetic resonance imaging (MRI) in multiple sclerosis (MS) patients.

Optimized 3D ultrashort echo time pulmonary MRI.
PURPOSE To optimize 3D radial ultrashort echo time MRI for high resolution whole-lung imaging. METHODS 3D radial ultrashort echo time was implemented on a 3T scanner to investigate the effects of: (1) limited field-of-view excitation, (2) variable density readouts, and (3) radial oversampling. Improvements in noise performance and spatial resolution were assessed through simulation and phanto...
متن کامل3D FLAIRED: 3D fluid attenuated inversion recovery for enhanced detection of lesions in multiple sclerosis.
Contrast optimization of a three-dimensional (3D) Fluid-attenuated inversion recovery (FLAIR) sequence is examined in the context of multiple sclerosis. In order to develop 3D FLAIR for enhanced detection of lesions, an iterative approach based on theoretical considerations was used. The 3D FLAIR sequence was systematically acquired with incremental parameter changes on a single subject with mu...
متن کاملWhite-matter lesions drive deep gray-matter atrophy in early multiple sclerosis: support from structural MRI.
BACKGROUND In MS, the relationship between lesions within cerebral white matter (WM) and atrophy within deep gray matter (GM) is unclear. OBJECTIVE To investigate the spatial relationship between WM lesions and deep GM atrophy. METHODS We performed a cross-sectional structural magnetic resonance imaging (MRI) study (3 Tesla) in 249 patients with clinically-isolated syndrome or relapsing-rem...
متن کاملCharacterization of the perivascular distribution of white matter lesions in multiple sclerosis phenotypes by 7T MRI
Introduction. Multiple sclerosis (MS) is a disease with profound heterogeneity in clinical course, and neuroradiological appearance of lesions both in white and gray matter (WM, GM). Histological data demonstrate that heterogeneous pathogenic mechanisms underlie the formation of MS-like demyelinating plaques, at least in WM, and identify four major patterns of demyelination (1). This pathogenic...
متن کاملWhite Matter Diseases YES, Multiple Sclerosis NO, Sjogren - Larsson Syndrome: Another Differential Diagnosis of Multiple Sclerosis
Sjogren-Larsson Syndrome (SLS) is an inherited autosomal recessive neurocutaneous disorder with congenital ichthyosis, spastic diplegia or quadriplegia and mental retardation. We report a case of Sjogren-Larsson Syndrome with clinical profile (mental retardation, ichthyosis, spastic diplegia) and MRI findings such as seen in multiple sclerosis (MS). So this rare syndrome can be another differen...
