Inclusion criteria

  • Pediatric patients 0-18 of age will be recruited by our surgical colleagues based on the clinical concern for craniosynostosis and possible need for calvarial reconstruction.

Exclusion criteria

Exclusion Criteria:

  • Lack of consent
  • /inability to undergo both examinations within the designated time period and/or undiagnostic image quality.
Terms in these criteria, in plain language(1)

Study arms

  • Experimental
    ZTE MRI Imaging

    Pediatric patients that have gotten a clinically indicated CT within a 6 week time period will receive a Zero Echo Time Magnetic Resonance Imaging (ZTE MRI)

    Diagnostic Test: Zero Echo Time Magnetic Resonance Imaging (ZTE MRI)

Interventions

  • Diagnostic testZero Echo Time Magnetic Resonance Imaging (ZTE MRI)

    Magnetic Resonance Imaging (MRI) with zero echo-time (ZTE) that uses proton density differences rather than T2 relaxation time differences to achieve contrast.

What researchers measure

Primary outcomes

  1. Number of Participants With 90% or Greater Concordance Between ZTE and CT Imaging Diagnosis

    In the context of our study, concordance refers to the level of agreement between two radiologists in their interpretation of imaging findings across the two modalities (ZTE and CT).

    Time frame: 1 Day
