Detaljert beskrivelse
Standard brain magnetic resonance imaging (MRI) is the gold-standard to diagnose acute ischemic brain injuries; however, it is not always feasible to obtain this standard MRI due to risks and contraindications. Some of the most common risks can include transport to the radiology department, especially with critically ill patients on life-saving medical devices, exposure to ionizing radiation, and contraindications can include incompatible surgical hardware in patients' bodies, amongst others.
Our institution has an FDA-cleared portable MRI (pMRI) by Hyperfine Research, Inc. (HRI). This device addresses many of the conventional MRI challenges by:
- Operating at very low magnetic field strengths strength (less than 0.2 T or approximately 10 times less than the field strength of conventional devices) and eliminating the need for special rooms or shielding. Family members and staff can remain at the patient's bedside.
- Minimizing conditions such as claustrophobia and anxiety with an open concept, transparent "helmet" to rest the head in during the exam.
- Portable and can maneuver through hospital environments and wheeled directly to a patient's bedside.
- Noise levels are substantially lower than conventional MRI systems, so hearing protection is optional for the patient. The sounds are described as vibrations that produce rhythmic tones.

Beskrivelse
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

Eksperimentell: Bærbar MR-arm
Alle fag som er påmeldt tilordnes arm 1

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