- presedation behavior [ Time Frame: day of sedation (day 1) ]Presedation behavior will be assessed on a 4-point scale, (by an anesthesiologist 1; who does not know which drug is administered): 1 = calm, cooperative; 2 = anxious but reasonable; 3 = anxious and not reasonable; 4 = crying or resisting. Categories 1 and 2 will be called "nondistressed behavior," and categories 3 and 4 will be defined as "distressed behavior."
- to determine optimal dose of propofol and thiopental during MRI [ Time Frame: day of sedation (day 1) ]The UMSS assigns a score of 0-4 based on the clinical assessment of the level of sedation as follows: 0 = awake and alert; 1 = minimally sedated: tired/sleepy, appropriate response to verbal conversation and/or sound; 2 = moderately sedated: somnolent/sleeping, easily aroused with light tactile stimulation or a simple verbal command; 3 = deeply sedated: deep sleep, arousable only with significant physical stimulation, and 4 = unarousable. Scores 3 will be accepted as procedural sedation and 4 will be accepted as deep sedation.
- UMSS score [ Time Frame: day of sedation (day 1) ]
- Side effects of sedation [ Time Frame: day of sedation (day 1) ]Side effects (apnea, nausea, vomiting, laryngospasm, emergence agitation) could occur during and after sedation will be recorded.
- recovery times [ Time Frame: day of sedation (day 1) ]Recovery time will be accepted as the period of time between the ends of MRI scan and reaching a UMSS score of 2 (by an anesthesiologist 2).

An initial bolus of 0.5 mg/kg of propofol will be administered over 1 minute. Supplementary boluses of propofol will be added until the UMSS score 3 are achieved.

Detailed Description:
This prospective, randomize, double-blind study will include 100 children, aged 6 month-12 years with ASA physical status I-II.
Children older than 3 years of age shall consume nothing by mouth (NPO) for solids and milk for at least 8 hours and children 6 months-3 years of age are NPO for solids and milk for 6 hours. Children will be allowed to receive breast milk until 4 hours before the beginning of the sedation. All the children will be allowed to take clear liquids up until 2 hours before the beginning of the sedation. To facilitate IV drug administration, EMLA cream will be applied on the dorsum of both hands 1 h before transfer to the preparation room.
Presedation behavior will be assessed on a 4-point scale, (by an anesthesiologist 1; who does not know which drug is administered): 1 = calm, cooperative; 2 = anxious but reasonable; 3 = anxious and not reasonable; 4 = crying or resisting. Categories 1 and 2 will be called "nondistressed behavior," and categories 3 and 4 will be defined as "distressed behavior." Patients will receive: group I; propofol 0.5 mg/kg or group II; thiopental 2.0 mg/kg, for anesthetic induction. After initial dose of the drug the sedation level of the children will be measured by the anesthesiologist 2 using the University of Michigan Sedation Scale (UMSS). The UMSS assigns a score of 0-4 based on the clinical assessment of the level of sedation as follows: 0 = awake and alert; 1 = minimally sedated: tired/sleepy, appropriate response to verbal conversation and/or sound; 2 = moderately sedated: somnolent/sleeping, easily aroused with light tactile stimulation or a simple verbal command; 3 = deeply sedated: deep sleep, arousable only with significant physical stimulation, and 4 = unarousable. Scores 3 will be accepted as procedural sedation and 4 will be accepted as deep sedation.
If a UMSS score of 3 will not be achieved after initial dose of propofol and thiopental, supplementary boluses of drugs will be added.
Mean arterial blood pressure (MAP), heart rate (HR), peripheral oxygen saturation (Spo2), and respiratory rate (RR) will be monitored continuously and be recorded at 5-min intervals during the study period by anesthesiologist 1. Patients will be allowed to breathe spontaneously without an artificial airway throughout the procedure. Oxygen will be administered via facemask.
Quality of the MRI will be evaluated by a radiologist using a three-point scale (1 = no motion; 2 = minor movement; 3 = major movement necessitating another scan).
Recovery time will be accepted as the period of time between the ends of MRI scan and reaching a UMSS score of 2 (by an anesthesiologist 2).
Side effects (apnea, nausea, vomiting, laryngospasm, emergence agitation) could occur during and after sedation will be recorded.
