Hyperpolarized 13C-pyruvate Metabolic MRI With Traumatic Brain Injury

Utility of Hyperpolarized 13C-Pyruvate Metabolic Magnetic Resonance Imaging in the Diagnosis of Early Cerebral Metabolic Crisis After Traumatic Brain Injury

Who can join

Ages 18 to 80 · All sexes · Healthy volunteers welcome

Inclusion Criteria:

* History of acute head injury with or suspected non-penetrating acute TBI
* Suitable to undergo contrast-enhanced MRI
* Negative serum pregnancy test

Exclusion Criteria:

* Inability to undergo MRI scan
* Inability to receive IV MRI contrast agents secondary to severe reaction or renal insufficiency
* Positive pregnancy test

About the study

The purpose of this study is to examine the safety and feasibility of using hyperpolarized metabolic MRI to study early brain metabolism changes in subjects presenting with head injury and suspected non-penetrating traumatic brain injury (TBI). This study will also compare HP pyruvate MRI-derived metrics in TBI patients with healthy subjects as well as Subarachnoid hemorrhage (SAH) patients to better understand if metabolic Magnetic resonance imaging scan (MRI) can improve our ability to diagnose a TBI.

The FDA is allowing the use of hyperpolarized \[1-13C\] pyruvate (HP 13C-pyruvate) in this study.

Up to 15 patients (5 with TBI, 5 with SAH, and 5 healthy volunteers) may take part in this study at the University of Maryland, Baltimore (UMB).
