Brief Summary
Traumatic Brain Injury (TBI) is a leading cause of death and disability among military personnel, Veterans, and civilians. One of the most dangerous complications of moderate-to-severe TBI is intracranial hemorrhage (ICH). If not identified and treated promptly, ICH can rapidly lead to worsening neurological damage or death. Current diagnostic tools, such as CT scans, are highly effective but impractical for battlefield or resource-limited environments due to their large size and infrastructure dependency. The Near-Infrared Detection-Head Imaging (NIRD-HI) system is an innovative, noninvasive device using Near-Infrared Spectroscopy (NIRS) to identify abnormal blood accumulation. Unlike traditional tools, NIRD-HI is compact, lightweight, and portable, making it suitable for remote or austere settings. By dynamically imaging the brain, it generates 3D visualizations that pinpoint the size and location of bleeds, including complex bilateral injuries. This offers a significant improvement over current point-of-injury technologies that lack the resolution to reliably diagnose all forms of ICH. This study supports the FY24 Combat Readiness Medical Research Program by advancing battlefield diagnostic and triage capabilities. The research will:
- Evaluate NIRD-HI's accuracy compared to CT imaging.
- Assess feasibility in real-world acute care settings.
- Investigate its ability to monitor changes in ICH over time. These objectives address the military's need for tools that improve rapid diagnosis and decision-making during emergencies. Implementing this research can revolutionize TBI management. For Service Members, NIRD-HI promises a field-ready solution for early detection, enabling faster intervention and more effective triage. By reducing diagnostic delays, it could save lives and prevent long-term complications. Furthermore, the system supports prolonged field care by providing continuous monitoring of evolving injuries. The benefits extend to civilian healthcare, particularly in rural or underserved areas lacking advanced imaging. This accessibility can improve trauma care outcomes for millions, reduce the burden on healthcare systems, and provide equitable distribution of life-saving technology. By addressing gaps in battlefield medicine, this project aims to enhance medical readiness and improve survivability in the most challenging environments.

Outcome Measures
Primary Outcomes (5)
Diagnostic Performance
Diagnostic Performance. Establish the sensitivity, specificity, PPV, and NPV of the NIRD-HI system for detecting ICH in TBI patients, with a target sensitivity and specificity exceeding 90%.
Baseline, at time of NIRD-HI testing administered
Feasibility Assessment - Scan Time
Time in minutes to complete scans in acute care setting recorded on a templated study log including scan start/stop time, interruptions and reasons for interruptions, technical errors and unanticipated device adverse events.
Enrollment through study completion, an average of 1 year
Feasibility Assessment - Operator Usability
Operator usability near the end of the recruitment period, 4-6 blinded clinicians (physicians and/or mid-level practritioners) will make a determination of criteria positive or negative research scans assigned in random order to establish statistics for inter-reader agreement. Blinded readers will assign a likelihood score using a Visual Analog Scale \[VAS\] to indicate how confident they are in their read.
Near the end of recruitment period, an average of 1 year
Feasibility Assessment - Device Integration
Device integration, through operator feedback questionnaire regarding ease of use.
Enrollment through study completion, an average of 1 year
Monitoring of ICH Progression
NIRD-HI readouts for the presence/absence of ICH and region of detection \[if positive\] as determined by the research device. NIRD-HI readouts will be correlated with Head CT results after each scan.
Baseline, at time of NIRD-HI testing administered
Secondary Outcomes (3)
Diagnostic Performance - Time Detection of ICH
Baseline, at time of NIRD-HI testing administered
Diagnostic Performance - Operator Performance
Baseline, at time of NIRD-HI testing administered
Accuracy of evolution testing [first NIRD HI scan vs. second NIRD HI]
Baseline, at time of NIRD-HI testing administered
Study Arms (2)
40 participants with positive head bleed on CT report
Subjects with positive head CT reports that may have a diagnosis of TBI or intracranial hemorrhage
40 participants with negative head bleed on CT report
Subjects without positive head CT reports that may have a diagnosis of TBI or intracranial hemorrhage
Interventions
All enrolled patients who meet the study's eligibility criteria will receive one NIRD-HI scan at the time of enrollment.
For patients requiring a planned repeat CT, a secondary NIRD-HI scan may be performed before the subsequent CT imaging.
Eligibility Criteria
Access to the proposed population includes a mixture of 15% active-duty military and/or VA patients and 85% civilians from central/southern Texas, including the 22 surrounding counties that are receiving trauma care at Brooke Army Medical Center. Daily review of the Trauma census will be conducted to review eligible patients. This screening tool will help determine, predict, and address challenges to recruitment.
You may qualify if:
- to 89 years of age
- Able to provide written informed consent either by self or legally authorized representative
- Received head CT imaging on admission
- Able to complete at least one NIRD-HI scan within 4 hours of head CT
- Non-operative management planned
You may not qualify if:
- Presence of penetrating or non-survivable injuries
- Hemorrhagic shock or large volume transfusion \[\>3 units of any blood product within
- hour of scan\]
- Large open skull wounds, scalp lacerations or surface hematomas prohibiting safe or comfortable sensor placement
- Presence of heat tattoos or intracranial metal fixtures
- Cervical injury prolonging C-spine collar
- Known prisoners or wards of state
- Any condition or finding that makes the patient unsuitable for image acquisition in the Investigator's opinion
