Role of MRI in multiple sclerosis I: inflammation and lesions.
Conventional magnetic resonance imaging (MRI) can improve accuracy in the diagnosis of multiple sclerosis (MS). Metrics derived from conventional MRI are now routinely used to detect therapeutic effects and extend clinical observations. Hyperintense lesions on T2-weighted MRI scans are related primarily to increased water content and thus cannot distinguish between inflammation, edema, demyelin...
متن کاملSegmentation of Multiple Sclerosis Lesions using Quantitative MRI
Introduction: A fast and reliable method to quantitatively measure the absolute water content of the human brain in vivo has been recently developed [1,2,3]. Simultaneously, parameter maps of T1 and T2* can be acquired. These quantitative parameter maps are very sensitive for the detection of subtle pathological changes in a variety of neurological diseases, such as multiple sclerosis (MS). Dur...
متن کامل[Approaches to segment multiple-sclerosis lesions on conventional brain MRI].
Different sets of criteria are currently used for the diagnosis of multiple sclerosis (MS). Some are based on clinical features, while others are related to imaging findings. Among the image processing systems, specific criteria include spatial dissemination of lesions in one image or their temporal dissemination in images acquired at different time points. In addition, the evolution of the les...
متن کاملHypothalamic lesions in multiple sclerosis.
Demyelinating lesions of fiber bundles in and adjacent to the hypothalamus (i.e. the fornix. anterior commissure, internal capsule, and optic system) may be the basis for autonomic and endocrine alterations in multiple sclerosis (MS) patients. Therefore we investigated the presence and immunological activity of lesions in hypothalamic fiber bundles of 17 MS patients and 14 controls. In the MS g...
متن کاملCortical lesions in multiple sclerosis.
Although previous studies have shown that the lesions of multiple sclerosis may involve the cerebral cortex, there is little published research on the prevalence and distribution of such lesions. Using neuropathological techniques and MRI, a series of studies has been undertaken in order to assess this, in particular to identify their relationship to cortical veins. A serial MRI study showed th...
