Abstract

 Introduction & Objective: MS is the most common disabling neurological disorder. Identifying new active MS plaques at the onset and clinical status and faster onset of treatment as well as evaluating the response to treatment is important and MRI with contrast is the best indicator for these measures.Materials & Methods: This study was cross- sectional including 62 patients with diagnosed MS. Whose clinical symptoms suggested the recurrence of MS. They were referred to the radiology department to undergo brain MRI with injection for the diagnosis of active plaques by a neurologist, The Data were analyzed using statistical tests and SPSS 21 software.Results: Based on the sequences of post contrast T1, pre contrast MTC and post contrast MTC 74, 272 and 271 plaques were respectively discovered. Detection of active MS plaques on T1 sequences after injection were in poor accordance and had significant difference with MTC before and after injection. Moreover, detection of active MS plaques on MTC sequences before injection were in good accordance and did not show significant difference with MTC sequences after injection.Conclusion: Based on these results, it seems that the purpose of MRI in MS patients is determining the amount of active plaques. Sequences of pre contrast and post contrast MTC are significantly more than sequences of post contrast T1. Therefore, using sequences of MTC can be helpful in MRI.
