Abstract

Magnetic resonance imaging (MRI) in preschool children is often challenging due to excessive motion artifacts. Sedation or general anesthesia (GA) is commonly used to prevent children from moving in the MRI scanner, with increased risk for cardiopulmonary complications and requirement for skilled personnel. Herein, we investigated whether oral melatonin, a natural hormone implicated in circadian rhythm regulation, could be used as an alternative sedation method prior to the MRI in preschool children with musculoskeletal problems. Fifteen children with suspected juvenile idiopathic arthritis underwent a total of 16 MRI examinations following administration of 10 mg of oral melatonin; satisfactory images were obtained in all but one case, with no adverse events.

Conclusion: The use of melatonin before the musculoskeletal MRI in preschool children is an effective, safe, and inexpensive alternative to standard sedation and general anesthesia in preventing motion artifacts.

What is Known:

• Magnetic resonance imaging (MRI) is a well-recognized diagnostic method to visualize synovial inflammation and changes of cartilage and bone in juvenile idiopathic arthritis.

• MRI examination requires sedation or general anesthesia to ensure immobility in children who are uncooperative.

What is New:

• Melatonin without sleep deprivation is efficacious and safe alternative to conventional sedation and general anesthesia before the musculoskeletal contrast-enhanced MRI in preschool children with JIA with timely insertion of intravenous cannula.
