What is Effect of MRI strength and propofol sedation on pediatric core temperature change about?

## Abstract ## Purpose: To determine core body temperature variations in children undergoing MRI exams on 1.5 Tesla (T) and 3T magnetic field strengths and with and without propofol sedation. ## Materials and Methods: Temporal artery temperatures were prospectively collected on 400 consecutive patients undergoing 1.5 Tesla (T) or 3.0T MRI scans. A cumulative logistic regression model was created using age, weight, MRI protocol, sedation status, pre‐MRI temperature and MRI strength to assess risk of temperature change. ## Results: For patients with complete pre‐ and post‐MRI temperature data, mean temperatures did not significantly change (−0.0155°C, 95%CI, −0.035, 0.064; n = 385). Temperature changes differed significantly between propofol‐sedated and nonsedated patients (−0.26°C ± .44 versus 0.24°C ± 0.42; __P__ 1°C; 12 were on the 1.5T. All 7 patients (1.8%) who increased >1°C were non‐sedates. ## Conclusion: Clinically significant core body temperature change is uncommon in children undergoing MRI with different magnetic field strengths, and with and without propofol sedation.
