title: [Comparison of four imaging examinations of shoulder joint injury in forensic expertise].
abstract: OBJECTIVE
  To compare the value of four imaging examinations, including the X-ray, CT, MRI and gas-iodine double contrast CT analyses, in the forensic expertise of shoulder joint injury.
  
  
  METHODS
  Imaging data of shoulder joint injury, by the X-ray, CT, MRI and gas-iodine double contrast CT were retrieved and analyzed.
  
  
  RESULTS
  The correct diagnosis rates of fracture and soft tissue injury by X-ray, CT and MRI were 52.8%, 72.0% and 63.2%, as well as 0.0%, 32.9% and 82.5%, respectively. The correct diagnosis rate of soft tissue injury by gas-iodine double contrast CT was 100%.
  
  
  CONCLUSIONS
  X-ray is a useful screening method, CT is better for diagnosis of fracture, and MRI is fit for diagnosis of soft tissue injury. Gas-iodine double contrast CT can reflect not only the soft tissue injury but also its severity. Thus, combined application of X-ray, CT, MRI and gas-iodine double contrast CT can provide important imaging information for forensic expertise in shoulder joint injury.
