How to Prove a Traumatic Brain Injury When MRI and CT Scans Are Normal: Legal and Medical Guidance
Written by Alex Zimmerman, Founding Partner at Hull & Zimmerman, P.C. Alex has over 30 years of experience representing traumatic brain injury victims across Colorado. He has successfully litigated TBI cases where standard imaging returned normal results, working alongside leading neurologists, neuropsychologists, and neuroradiologists to build compelling evidentiary records for his clients.
Proving a traumatic brain injury (TBI) can be particularly challenging when traditional imaging techniques like MRI and CT scans yield normal results. Many individuals suffering from TBIs experience debilitating symptoms that are not always visible on standard imaging tests. This article aims to provide comprehensive guidance on how to effectively demonstrate the existence of a TBI despite normal imaging findings. Readers will learn about specialized testing options, the importance of symptom documentation, and the role of expert evaluations in supporting their claims. Additionally, we will explore the legal avenues available for those seeking compensation for their injuries, particularly through the expertise of legal professionals like Hull and Zimmerman PC, who specialize in TBI cases. Hull & Zimmerman has a strong track record of working with Colorado neurological experts to build robust cases for clients with normal imaging results.
Research further highlights the limitations of standard MRI in diagnosing mild traumatic brain injury and predicting recovery.
MRI Limitations & Neuropsychological Testing in Mild TBI
Mild traumatic brain injury (MTBI) is a common reason for hospital attendance and is associated with significant delayed morbidity. We studied a series of 80 persons with MTBI. Magnetic resonance imaging (MRI) and neuropsychological testing were used in the acute phase and a questionnaire for post-concussion syndrome (PCS) and return to work status at 6 months. In 26 subjects abnormalities were seen on MRI, of which 5 were definitely traumatic. There was weak correlation with abnormal neuropsychological tests for attention in the acute period. There was no significant correlation with a questionnaire for PCS and return to work status. Although non-specific abnormalities are frequently seen, standard MRI techniques are not helpful in identifying patients with MTBI who are likely to have delayed recovery.

The following sections will cover essential strategies for proving a TBI, including the significance of timely action, the types of medical evidence required, and the support systems available for victims.
Seek Specialized Testing
When standard imaging fails to reveal a TBI, seeking specialized testing becomes crucial. Advanced neuroimaging and diagnostic modalities provide deeper insights into brain function and structure that traditional MRI and CT scans may miss. These include:
- Diffusion Tensor Imaging (DTI): DTI maps the brain’s white matter tracts and is highly sensitive in detecting diffuse axonal injury, which is often invisible on standard MRI scans. This technique measures the integrity of neural pathways and is increasingly accepted as reliable evidence of TBI in Colorado courts.
- Functional MRI (fMRI): Unlike structural MRI, fMRI measures brain activity by detecting changes in blood flow, revealing functional deficits even when anatomical scans appear normal. This modality helps identify areas of the brain with impaired function following trauma.
- Positron Emission Tomography (PET) Scans: PET scans assess metabolic activity in brain tissue, detecting hypometabolism in regions affected by TBI. This metabolic information can highlight areas of dysfunction not visible on structural imaging.
- Single Photon Emission Computed Tomography (SPECT) Scans: SPECT measures cerebral blood flow and can reveal perfusion deficits in TBI patients who have normal structural imaging results, providing evidence of brain injury through functional abnormalities.
- Quantitative Electroencephalography (qEEG): qEEG records brainwave patterns and can identify dysregulation consistent with TBI, offering objective data on brain electrical activity alterations post-injury.
- Neuropsychological Testing: Standardized test batteries such as ImPACT, RBANS, Trail Making Test, and Stroop Test objectively measure cognitive deficits including memory, attention, processing speed, and executive function. These test results are admissible as evidence in Colorado personal injury cases and are critical in demonstrating the functional impact of TBI.
Further research supports the efficacy of advanced imaging techniques in revealing the organic basis of TBI, even when standard MRI appears normal.
Proving TBI with Normal MRI: New Modalities & Cognitive Impairment
There is evidence that MTBI patients with true traumatic MRI lesions are neuropsychologically different from MTBI patients with nonspecific MRI lesions or normal brain MRI. These results support the hypothesis that some acute MTBI signs and symptoms have a real organic basis which can be detected by selected new MRI modalities.

Additionally, advanced neuropsychological assessments can evaluate cognitive deficits that may not be apparent through imaging alone. These tests can help establish a clearer picture of the injury’s impact on daily functioning, which is vital for both medical treatment and legal claims.
Document Symptoms
Thorough documentation of symptoms is essential for proving a TBI, especially when imaging results are normal. Individuals should keep a detailed log of their symptoms, noting their frequency, intensity, and impact on daily life.
Key symptoms to document include:
- Cognitive Issues: Memory problems, difficulty concentrating, and confusion.
- Emotional Changes: Mood swings, anxiety, and depression.
- Physical Symptoms: Headaches, dizziness, and fatigue.
Maintaining a symptom diary can provide valuable evidence to support claims and help healthcare providers understand the full extent of the injury.
Gather Medical Evidence
Collecting comprehensive medical evidence is vital in substantiating a TBI claim. This includes obtaining medical records, treatment notes, and any diagnostic tests performed.
Important types of medical evidence to gather include:
- Emergency Room Records: Documentation of initial assessments and treatments.
- Follow-Up Care Notes: Records from specialists, such as neurologists or psychologists.
- Test Results: Any neuropsychological evaluations or specialized imaging results.
Linking symptoms to medical evidence strengthens the case for a TBI, especially when traditional imaging does not show visible damage.
Consult with Experts
Engaging with medical and legal experts can significantly bolster a TBI claim. Medical professionals specializing in brain injuries can provide critical evaluations and testimony regarding the nature and extent of the injury.
Types of experts to consult include:
- Neurologists: For medical evaluations and treatment recommendations.
- Neuropsychologists: For cognitive assessments and expert testimony on the impact of the injury.
- Legal Experts: Attorneys specializing in personal injury law can guide individuals through the complexities of filing a claim.
Expert testimony can be pivotal in establishing the legitimacy of a TBI claim, particularly when imaging results are inconclusive.
Colorado Legal Evidence Standards for TBI Cases Without Imaging
In Colorado, the legal standard for proving a traumatic brain injury is the preponderance of the evidence, meaning it must be more likely than not (at least 51%) that the injury occurred and caused the claimed impairments. Colorado courts have increasingly accepted advanced diagnostic tools and expert testimony as sufficient evidence of TBI even when CT and MRI scans are normal.
Neuropsychological testing, DTI imaging, and expert witness testimony play a critical role in meeting this standard. A neurologist or neuropsychologist who can explain to a jury why normal structural imaging does not exclude brain injury is often the most important witness in mild TBI cases.
Hull & Zimmerman builds a comprehensive evidentiary record by compiling medical records, specialist reports, neuropsychological test results, symptom journals, employer records demonstrating cognitive decline, and family or witness testimony. This multi-faceted approach strengthens the case and aligns with Colorado’s evidentiary requirements.
Legal Guidance
Navigating the legal landscape surrounding TBI claims can be complex, especially when traditional imaging fails to provide clear evidence of injury. Legal standards for proving a TBI often require a combination of medical documentation, expert testimony, and symptom logs.
The historical debate surrounding the underlying causes of mild traumatic brain injury symptoms underscores the complexity of legal proof in these cases.
Legal Challenges: Physiogenic vs. Psychogenic mTBI Proof
Historically, two divergent positions on the long-term impact of mild traumatic brain injury (mTBI), also commonly termedconcussion(Ruff, Iverson, Barth, Bush, & Broshek,2009), existed in the scientific literature. One stance was that a relatively small percentage of mTBI patients experience lasting problems forphysiogenic(i.e., medically verifiable, neurological, or physical) reasons. The second view was that residual problems arising from mTBI are morepsychogenic(i.e., medically unverifiable, non-neurological, or psychological). Uzzell (1999) and Ruff, Camenzuli, and Mueller (1996), for example, were in the former camp, whereas others, including Binder (1997) and Larrabee (1999), leaned away from a neurological causation explanation for residual problems, pending more rigorous scientific investigation.
