Study Details

Brief summary:

This study will evaluate the sensitivity and specificity of low field portable MRI (pMRI) for detection of hypoxic ischemic brain injuries in pediatric patients compared to clinically obtained neuroimaging to define pediatric diagnostic limitations and to determine the diagnostic capabilities of this neuroimaging modality following optimization of image acquisition. The results of this study will help determine optimal clinical implementation opportunities in pediatric patients.

Eligibility Criteria

Sex: All

Age: 0 - 17

Healthy Volunteers: Not accepted

Inclusion Criteria

  • Patients hospitalized in the Pediatric Intensive Care Unit, Cardiac Intensive Care Unit, or the Neonatal Intensive Care Unit
  • Ages 0-17 years at study enrollment
  • Acute neurologic deficit suspected secondary to Hypoxic Ischemic Brain Injury (HIBI) or patients at high risk for HIBI

Exclusion Criteria o Pregnancy Any patient who has a contraindication to having an MRI

Patients with a passive or active implant will:

•First be reviewed on MRISafety.com to determine MR conditionality •If device is listed as Conditional or Unsafe for a 1.5T or a 3T, device will then be reviewed by MRI Safety Officer or MRI Physician Section chief to determine true conditionality for the portable MRI

Interventions and Outcome Measures

Arms

experimental: Portable MRI Arm

All subjects enrolled with be assigned to Arm 1

Interventions

Portable MRI

Enrolled subjects will undergo a portable, ultralow-field MRI (pMRI) at the bedside in the ICU location within +/- 24 hours of a clinically obtained, conventional MRI and/or head CT

Scavenged Sample Collection

Remaining blood or cerebrospinal fluid samples from clinical testing will be scavenged at timepoints correlating to the radiology imaging.

Primary outcome measure

  • Determine the sensitivity and specificity of pMRI for detection of acute pediatric focal ischemic brain injuries. [ Time Frame: During intensive care admittance, an average of 1 month ]
