Magnetic resonance and sclerosis multiplex

Magnetic resonance (MR) imaging started to be in exacting diagnostic process of multiple scleroris (MS) an important supporting examination method that in 2001 was included into diagnostic criteria (McDonald criteria SM 2001). Following these criteria passed a modification in 2005 and 2010 with an aim to increase their sensitivity at preserving their specificity. MR is at present the most used biomarker in the process of diagnosis, at determination of prognosis and monitoring of disease progression, using conventional and non conventional techniques. Into conventional techniques belong T1 weighted images without or with administration of a contrast medium, T2 weighted images (T2vo) from which postprocessing at using of soft cuttings, the volume of lesions can be determined (e. g. lesion load) for watching of inflammation or at neurodegeneration turn, at patient we can measure the brain atrophy. The non conventional techniques are exercised in experimental works, that examine the pathologic process in MS eventually are applied in diagnosis and differential diagnosis.
