Imaging cortical lesions in multiple sclerosis with ultra-high-field magnetic resonance imaging.
OBJECTIVE To determine the sensitivity of T2*-weighted gradient-echo (T2*GRE) and inversion recovery turbo-field-echo (TFE) sequences for cortical multiple sclerosis lesions at 7 T. DESIGN, SETTING, AND PARTICIPANTS Autopsied brain tissue from individuals with multiple sclerosis was scanned with 3-dimensional T2*GRE and 3-dimensional inversion recovery white matter-attenuated TFE sequences at...
متن کاملFirst clinical study on ultra-high-field MR imaging in patients with multiple sclerosis: comparison of 1.5T and 7T.
BACKGROUND AND PURPOSE Higher magnetic field strengths and continuous improvement of high-resolution imaging in multiple sclerosis (MS) are expected to provide unique in-vivo and non-invasive insights in pathogenesis and clinical monitoring. The purpose of this study was to investigate the potential of high-resolution imaging of MS lesions in vivo comparing 7T with conventional 1.5T. MATERIAL...
متن کاملUltra - high field imaging techniques for MRA
• Performing magnetic resonance angiography (MRA) at higher fields has been demonstrated to improve the signal to noise and contrast to noise in both the brain and body applications. • Direct implementation of standard clinical protocols and acquisitions methods at 7T are insufficient to obtain the best results as increased B0 and B1+ inhomogeneity, local SAR and limited peak power present road...
متن کاملUltra-high-field magnetic resonance imaging
Understanding human brain function, brain development and brain dysfunction is one of the great challenges of the twentyfirst century. Biomedical imaging has now run up against a number of technical constraints that are exposing limits to its potential. In order to overcome the current limits to high-field magnetic resonance cerebral imaging (MRI) and unleash its fullest potential, the CEA has ...
متن کاملAn Ultra-High Field Study of Cerebellar Pathology in Early Relapsing-Remitting Multiple Sclerosis Using MP2RAGE.
OBJECTIVES The aim of this study was to study focal cerebellar pathology in early stages of multiple sclerosis (MS) using ultra-high-field magnetization-prepared 2 inversion-contrast rapid gradient-echo (7T MP2RAGE). MATERIALS AND METHODS Twenty early-stage relapsing-remitting MS patients underwent an MP2RAGE acquisition at 7 T magnetic resonance imaging (MRI) (images acquired at 2 different ...
