The study is aimed to reassess the role of CT in detecting various epileptogenic lesions with multi detector CT imaging, to know the value of CECT is evaluation of various lesions and to know the commonest CNS lesions causing afebrile seizures in Paediatric age group is the local population. METHODOLOGY: The study consists of 70 Pediatric patients suffering from afebrile seizures referred to Radio – diagnostic department S.V.R.R. Hospital at Tirupati for C.T. brain investigation. EXCLUSION CRITERIA: As our study is to evaluate epilepsy characterized by recurrent (more than two episodes) seizures, with no immediate identifiable and avoidable cause (sleep deprivation), known metabolic disorders, alcohol withdrawal, pyrexia. Therefore we excluded patients below one month ago. Febrile convulsions, acute infections, toxic and known metabolic disorders Equipment used is Fourth generation Four slice CT with scan time 0.7 seconds Matrix size 640, gantry tilt 120, KV – 120 MAs – 100 to 200, Slice thickness 5mm and 2mm Auto power injector 3 to 3.5 ml per second. NECT: Continuous axial sections of brain, posterior fossa 3mm and rest of brain 5mm sections and 2mm sections were taken wherever necessary CECT is carried out logically in those cases which were inconclusive or ambiguous and NECT excluding more definite cases like congenital anomalies and calcified granulomas without peri lesion edema. IV CONTRAST: Non-ionic contrast medium at 1mg/ kg body weight was used whenever indicated, no adverse reactions were noted after injection of contrast medium and sedation was advised whenever the patient was un co-operative.
