Can QuickBrain MRI replace CT as first-line imaging for select pediatric head trauma?

Area of Science:

• Pediatric Radiology
• Emergency Medicine
• Neurotrauma

Background:

• Computed tomography (CT) is standard for pediatric traumatic brain injury (TBI) but involves radiation exposure.
• There is a need for safer, effective neuroimaging alternatives in pediatric emergency care.

Purpose of the Study:

• To evaluate the efficacy of a QuickBrain MRI (qbMRI) protocol for detecting clinically important TBIs in pediatric emergency department patients.
• To compare qbMRI's ability to identify radiographic TBIs against CT scans.

Main Methods:

• Prospective study of 73 pediatric trauma patients (<15 years) with suspected TBI.
• Patients underwent both CT and qbMRI in the acute setting.
• Clinically important TBI defined by need for surgery, prolonged ICU stay, or death.

Main Results:

• qbMRI had a median acquisition time of under 5 minutes.
• Sensitivity for clinically important TBI was 95% (95% CI = 77%-99%).
• Sensitivity for any radiographic injury was 89% (95% CI = 78%-94%).

Conclusions:

• qbMRI demonstrates high sensitivity for detecting clinically important traumatic brain injuries in children.
• Further multi-institutional trials are recommended to validate these findings and support qbMRI adoption.
