About

This hypothesis-generating feasibility study to determine potential associations between a broad range of clinical neurological symptoms and Magnetic Resonance Image (MRI), data, and clinical findings involved in mild traumatic brain injury (mTBI). These associations will be examined over the acute and sub-acute period (baseline to 3 months) following injury to provide information useful for optimization of MR pulse sequences for mTBI applications.

The intent of this study is to broadly generate a range of potential mTBI biomarkers detectable using investigational MR pulse sequence technologies. Feasibility data attained in this study may be used for engineering program decision-making and in support of future scientific assessment, engineering development, published research databases or registries mTBI data and images, and other purposes determined by the Sponsor. The results of this study are not intended for use in regulatory submissions.

Subjects will be examined on commercially available MR scanner using investigational or standard of care MR coils and a series of investigational Application Packs containing a predetermined set of MR pulse sequences optimized by Sponsor

Full description

This hypothesis-generating feasibility study is being conducted to determine potential associations between a broad range of clinical neurological symptoms and MR images, data, and clinical findings involved in mild traumatic brain injury (mTBI). These associations will be examined over the acute and sub-acute period (approximately 3 months) following injury to provide information useful for optimization of MR pulse sequences for mTBI applications.

Subjects will be examined on commercially available MR scanners using investigational or standard of care MR coils and a series of investigational Application Packs containing a predetermined set of MR pulse sequences optimized by GEHC.

Segment 1 (mTBI patient) Inclusion and Exclusion Criteria Inclusion Criteria for mTBI subjects

Subjects included in the main part of this study (Segment 1) will:

Be aged ≥15 and ≤50 years old at the time of enrollment;
Be diagnosed with mTBI according to the standard diagnostic procedures at the investigational site in a timeframe that meets enrollment criteria for enrollment in one of the first two intervals of the study, as follows:
1. Meets criteria for enrollment in Encounter 1 (within 72 hours), or
2. Meets criteria for enrollment in Encounter 2 (within 8±2 days)
Be capable of sufficiently clear communication to allow the subject to provide written informed consent, or assent with parental or guardian consent for minors as described in Section 6.3 - Protection of Vulnerable Subjects, for participation in all parts of the study.

That are unable or unwilling to complete study procedures accurately or have any conflict of interest that could affect study results, in the opinion of the investigator;
Contraindications to MRI scanning, including:
1. Current or suspected pregnancy per site clinical practice;
2. Other conditions that may constitute a hazard to the subject during study participation, determined by the investigator;
3. Inability to comply with any part of the site's MR safety policy.

1. Age,
2. Gender,
3. Sociodemographic characteristics, and
4. Handedness.
Be capable of sufficiently clear communication to allow the subject to provide written informed consent, or assent with parental or guardian consent for minors as described in Section 6.3 - Protection of Vulnerable Subjects, for participation in all parts of the study.
