Brain MRI without anesthesia in children less than 3 months old

Area of Science:

• Pediatric Radiology
• Neuroimaging
• Infant Care

Background:

• General anesthesia in infants poses short- and long-term risks.
• Alternative methods for infant neuroimaging are needed to mitigate these risks.

Purpose of the Study:

• To evaluate the efficacy of brain MRI without general anesthesia in infants under 3 months old.
• To assess the safety and success rate of a non-anesthetic immobilization technique.

Main Methods:

• A prospective case-control study involving infants under 3 months requiring brain MRI.
• Infants were fed to sleep and immobilized with a pillow; controls received general anesthesia.
• Three pediatric radiologists assessed MRI success, repeat necessity, and motion artifacts.

Main Results:

• 89% of brain MRIs in the non-anesthesia group were successful.
• Optimal MRI quality was achieved in 60% of cases, with no detected safety issues.
• This technique avoided general anesthesia for 47 infant MRI studies.

Conclusions:

• Brain MRI can be safely and effectively performed in infants under 3 months without general anesthesia.
• The feed and sleep technique with pillow immobilization is a viable alternative.
