Cranial vault imaging for pediatric head trauma using a radial VIBE MRI sequence

Area of Science:

• Medical Imaging
• Radiology
• Pediatric Imaging

Background:

• Head trauma is a common reason for CT scans in children.
• Assessing cranial vault fractures often relies on CT imaging.

Purpose of the Study:

• To evaluate the feasibility of a 5-minute 3D golden-angle (GA) VIBE MRI sequence for imaging cranial bones.
• To compare the diagnostic accuracy of GA-VIBE MRI with CT for identifying cranial vault fractures in pediatric patients.

Main Methods:

• A pilot study included pediatric patients (<18 years) with head trauma.
• Clinicians assessed CT and GA-VIBE MRI images (volumetric and 3D reconstructions) for image quality and fracture detection.
• A 5-point Likert scale was used to rate image acceptability and fracture presence.

Main Results:

• Thirty-one patients underwent both CT and GA-VIBE MRI.
• 97% of MRI reviews found image quality acceptable for diagnosis.
• GA-VIBE MRI demonstrated 100% sensitivity and specificity for detecting cranial vault fractures, with no discrepancies compared to CT.

Conclusions:

• The 5-minute GA-VIBE MRI sequence produces clinically acceptable cranial images.
• GA-VIBE MRI is highly accurate in detecting cranial vault fractures in pediatric head trauma patients.
• This MRI technique shows potential as an alternative to CT for evaluating pediatric cranial injuries.
