Diagnostics for TBI


The WAVi Desktop Report is provided as a service to allow your clinician to combine brain measurements with standard assessments. While not intended to be a diagnosis, the WAVi report gives you a snapshot of your brain function. Just as a stopwatch can be used by an athlete to measure results, the WAVi tests can be used to track your brain performance over time.  

Nuclear Spect Imaging

How to Read a SPECT Scan

The blue represents lack of blood flow; the green, yellow, and red indicates blood flow.

The diagnostic basis of using neuroimaging scans (routine MRI or CT scan) is inadequate for the determination of the traumatic brain injury or its degree of injury. Quoting Flanagan et al. (2008) in “Traumatic brain injury: Future assessment tools and treatment prospects” in the journal Neuropsychiatric Disease and Treatment:

Traditional imaging techniques, such as computerized tomography (CT) and conventional magnetic resonance imaging (MRI) have proven to be highly effective in identifying macroscopic lesions, which is a necessary component in managing acute trauma.  …[However], individuals with mild TBI often have normal appearing neuroimaging studies despite manifesting cognitive and behavioral problems. Given the limitations of conventional imaging technologies, it is not surprising that they are poorly prognostic of outcomes (Diaz-Marchan et al 1996) and offer little information regarding the assessment of efficacy of TBI-related treatments. (p. 878)

Nuclear SPECT scans have the unique ability to assess cerebral perfusion and provide solid medical and legal evidence for the diagnosing the extent of a TBI.  (Of note, in 2012, Judge Donald W. Malloy, a United States District Court Judge in the Missoula Division of the U.S. District Court in Montana filed an opinion upholding the admissibility of a SPECT scan).


We recommend Cerescan in Denver for cases involving courts and attorneys.


A severe traumatic brain injury per the DSM-V (2013) 
DSM-V Diagnostic Criteria for Major or Mild Neurocognitive Disorder Due to Traumatic Brain Injury:

  • The criteria for major or mild neurocognitive disorder must be met.
  • There is evidence of a traumatic brain injury—that is, an impact to the head or other mechanisms of rapid movement or displacement of the brain within the skull, with ONE or more of the following:
  • Loss of consciousness (LOC).
  • Posttraumatic amnesia (PTA).
  • Disorientation and confusion.
  • Neurological signs (e.g., neuroimaging demonstrating injury; a new onset of seizures; a marked worsening of a preexisting seizure disorder; visual field cuts; anosmia (loss of smell); hemiparesis).
