Abstract :

Aims and objectives

To evaluate the role of Magnetic resonance imaging (MRI) in partial seizures and to correlate the MRI findings with EEG (Electroencephalogram)

Materials and methods

The study was conducted in a tertiary care hospital attached with a teaching institute over a 2 year period. 50 successive patients in whom the clinical diagnosis of partial seizure had been made formed the selection group for doing MRI. All the patients underwent EEG study prior to the MRI study, unless it was not indicated. The EEG and magnetic resonance imaging findings were correlated with postoperative histopathological findings in cases where required.

Results

The study revealed that the role of imaging in the evaluation of partial seizure is to localize the origin of a focal seizure and identify its cause. Magnetic Resonance Spectroscopy and intravenous contrast administration helps in better characterization of the lesions and thus improves the reliability and confidence of diagnosis in lesions with non–specific appearances.

Conclusion

MRI should be the imaging study of choice for the assessment of all patients with partial seizures irrespective of the EEG findings.
