title: Imaging in Chronic Traumatic Encephalopathy and Traumatic Brain Injury.
abstract: BACKGROUND
  The diagnosis of chronic traumatic encephalopathy (CTE) can only be made pathologically, and there is no concordance of defined clinical criteria for premorbid diagnosis. The absence of established criteria and the insufficient imaging findings to detect this disease in a living athlete are of growing concern.
  
  
  METHODS
  The article is a review of the current literature on CTE. Databases searched include Medline, PubMed, JAMA evidence, and evidence-based medicine guidelines Cochrane Library, Hospital for Special Surgery, and Cornell Library databases.
  
  
  METHODS
  Clinical review.
  
  
  METHODS
  Level 4.
  
  
  RESULTS
  Chronic traumatic encephalopathy cannot be diagnosed on imaging. Examples of imaging findings in common types of head trauma are discussed.
  
  
  CONCLUSIONS
  Further study is necessary to correlate the clinical and imaging findings of repetitive head injuries with the pathologic diagnosis of CTE.
