About

Our project aims to develop a rapidly acquired and communicated MRI assessment and report that incorporates functional and structural imaging to convey information about functional neurological insults following traumatic brain injury (TBI) that are not typically visible on clinical imaging. Within this framework, there are two sub-studies. The first is a prospective study of patients with TBI who will have an MRI in the sub-acute period after their injury, followed by clinical assessments up to 90 days post-injury. A model will be developed to link MRI biomarkers to persistent symptoms of TBI. The second sub-study will use a focus group methodology to develop the report content and format with input from several groups of stakeholders.

Full description

Traumatic brain injury (TBI) can range from mild (mTBI) to moderate and severe (msTBI), and 69 million individuals worldwide sustain a TBI annually. There are many unanswered questions related to the diagnosis of TBI, the prediction of recovery, and the selection of effective treatments. For a subset of patients with TBI, persistent symptoms (PS) can substantially reduce quality of life. Particularly for mTBI, these impairments occur frequently without evidence of structural damage to the brain on MRI or CT. The lack of objective evidence of damage can limit a patient's access to clinical resources, insurance coverage and compensation related to their injury.

Furthermore, clinicians often have difficulty predicting TBI patients' course and extent of recovery. Preliminary evidence suggests that combining several novel types of MRI techniques may enable the detection of changes in individuals with TBI and provide information about patient recovery. Therefore, our proposed research project will assess individuals with TBI using novel MRI and a battery of assessments that examine how they function (functional assessments) in the acute stages after injury with a complete reassessment of function three months after injury. These procedures will be performed in 200 patients. Overall, this project will incorporate TBI survivors, family members/caregivers, clinicians, and members of the legal/insurance community to address four goals:

To develop reports for survivors and their supporters to communicate MRI and functional assessment findings. This report will help survivors understand their injuries and symptoms and suggest treatments. Additionally, a more technical report will be developed for clinicians and legal/insurance personnel to support diagnosis, direct testing, and aid in choosing therapeutic approaches. Focus groups will be conducted for each group to develop the report content and format.
To link MRI findings to neurological function and symptoms. The use of several MRI sequences increases our ability to identify deficits. However, this large amount of information may be difficult for a clinician to review, synthesize and use to predict patient function. The investigators developed a method to summarize the MRI data into intuitive outputs to address this. These outputs are linked to function and allow clinicians and patients to connect the damage detected by MRI to impairments in function.
To develop a tool to assess the risk of PS 90 days after injury using MRI and clinical data collected early after injury.
To develop a comprehensive MRI protocol that can be performed within the shortest possible time on any clinical MRI scanner to make this testing widely accessible. For the complete MRI protocol used in this study, the total time will be 45 minutes, with five types of MRI collected. The investigators will perform analyses where one or more MRI types is removed from the analysis to understand whether all types collected are necessary to achieve the outcome. This will allow us to reduce the scan time as the clinical protocol is developed.

Findings from this work will be impactful for the following reasons: (1) the development of a report will allow patients and caregivers to be more informed about their path to recovery; (2) the development of an accessible clinical protocol and report will allow clinicians to access functional neuroimaging; (3) a protocol that links functional neuroimaging changes to functional impairment will provide evidence that injury is linked to signs/symptoms in TBI; (4) identification of patients at risk for PS combined with a comprehensive functional evaluation in the acute stages of injury will allow clinicians to focus on early therapy to prevent PS; and (5) development of the shortest possible protocol for data acquisition that increases patient comfort and increases accessibility to functional neuroimaging in the clinical setting.
