Efficacy of Low Dose Propofol Given at the End of Sevoflurane Anesthesia for Prevention of Emergence Agitation in Pediatric Patient Undergoing MRI Scan

The goal of this clinical trial is to compare Efficacy of low dose propofol(0.5 mg/kg) vs placebo given at the end of sevoflurane anesthesia for prevention of emergence agitation in pediatric patient undergoing MRI scan. The main question it aims to answer is "Can low dose propofol reduce the incidence of emergence agitation after general anesthesia?" Participants will be given propofol 0.5 mg/kg or saline according to the allocated group at the completion of MRI scan
