The correlative relationship between AEEG and MRI in the diagnosis of epileptic patients / 中华神经科杂志

ABSTRACT

Objective To analyse the role of AEEG and MRI in diagnosis of epilepsy on its primary epileptic focus and pathologic lesions. Methods We reviewed the results of sixty epileptic patients on routine EEG, twenty-four hour active EEG(AEEG),CT scanning and MRI examinations. The relationship between epileptic discharges of AEEG and lesions of MRI was analyzed by using ? 2 test. Results AEEG showed a higher sensitivity in finding epileptic focus in 80% patients, as compared with the rate of 32% in routine EEG. The sensitivity on finding the cerebral lesion related to the epileptic focus by using MRI was 60%, as compared with the rate of 33% in CT scanning. There was a correlative relationship between the AEEG discharge foci and the lesions found by MRI( P
