Trial Title: Two Anesthetic Techniques in Magnetic Resonance Imaging (MRI)

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: HEALTH_SERVICES_RESEARCH
- Time Perspective: None
- Masking: NONE
- Phase: PHASE1
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Subjects presenting as out-patients, scheduled to receive an anesthetic for MRI of body (spine, chest, abdomen, and/or pelvis) and/or extremity (arm and/or leg).~2. The subject must be a candidate for both anesthetic techniques. This decision will be made by a staff member of the Department of Anesthesiology. This staff member will not be a member of the study team and will obtain the consent for Anesthesia.~3. The subjects must be 12 months to 7 years (inclusive of the seventh year).~4. The subject's legally authorized representative has given written informed consent to participate in the study.~Exclusion Criteria:~1. The subject is residing in the Pediatric Intensive Care Unit, the Cardiac Intensive Care Unit, or Neonatal Intensive Care Unit.~2. Anxiolytic medication is ordered before the MRI (e.g., midazolam or ketamine).~3. The subject has a history or a family (parent or sibling) history of malignant hyperthermia.~4. The subject has life-threatening, medical conditions (American Society of Anesthesiologists Physical Status 4, 5 or 6).~   * The American Society of Anesthesiologists (ASA) classification scale is a measure of physical status or how healthy the patient is.~  * For our study, we will focus on children which are defined as ASA I, II or III which means a healthy child (ASA I), a child with a systemic disease that is mild and well controlled (ASA II) or a child with systemic disease that is severe and controlled (ASA III).~5. The subject is allergic to or has a contraindication to any of the drugs used in the study.~6. The subject has previously been treated under this protocol.~7. The subject has a tracheostomy or other mechanical airway device.~8. The subject has received within the past 12 hours an oral or intravenous alpha-adrenergic, beta-adrenergic agonist, or antagonist drugs (e.g., clonidine, propranolol, albuterol).~9. The subject is not scheduled to receive anesthesia-sedation care for the MRI.~10. The subject received one of the anesthetic regimens for the same MRI during the past six months.

Study Arms:
- dexmedetomidine (Type: ACTIVE_COMPARATOR): Determine if there is a significant difference in the quality of care between our two standard anesthesia techniques for children undergoing a MRI of the body and/or extremity MRI.
- propofol (Type: ACTIVE_COMPARATOR): Determine if there is a significant difference in the quality of care between our two standard anesthesia techniques for children undergoing a MRI of the body and/or extremity MRI.

Based on this trial design, predict the completion outcome and termination type (if applicable).
