Role of Magnetic Resonance Imaging in the Evaluation of Partial Seizures
Journal Title: ​International Journal of Contemporary Medicine surgery and Radiology - Year 2018, Vol 3, Issue 1
Abstract
Introduction: It is important to identify the neuroimaging features that are associated with status epilepticus. Advances in technology to localize focal epileptogenic substrates, especially that of high-resolution structural imaging with magnetic resonance imaging (MRI), have substantially improved the success of surgical treatment. The present study evaluates the efficacy of magnetic resonance imaging in the evaluation of patients with Partial Seizures. Material and Methods: The present study was conducted among 50 patients with history of partial seizures. All patients underwent magnetic resonance imaging. The epileptogenic substrates were identified on the basis of the signal intensities and morphological abnormalities seen on magnetic resonance imaging. Data was collected through both interview and observation. The statistical test that was used is chi square with p value <0.05 considered as significant value. Results: In our study, mesial temporal sclerosis was the most common abnormality identified in 30% of the study group, followed by gliosis seen in 27% of the seizure patients. Among patients with complex partial seizures, 22 patients had lesions detected in magnetic resonance imaging. The diagnostic yield in the partial seizure group is 73%. Conclusion: Magnetic resonance imaging along with clinical history and electroencephaography should be used in the initial assessment of patients who are considered surgical candidates, since the presence of focal and, in particular, medial temporal lobe pathology increases the chances of progression to successful surgical treatment.
