title: [Comparison of irradiation for tomosynthesis and CT of the wrist].
abstract: OBJECTIVE
  Tomosynthesis is a novel imaging modality based on the use of flat-panel detector technology. Its impact in the evaluation of the post-traumatic wrist has yet to be defined. The low associated radiation dose is one of its main advantages. Comparison of radiation doses between tomosynthesis, radiographs and CT is thus necessary.
  
  
  METHODS
  The delivered doses for a five-view wrist radiographic examination, frontal and lateral tomosynthesis and CT were measured using radiothermoluminescent dosimeters.
  
  
  RESULTS
  Biplane tomosynthesis has the lowest delivered dose with 25% less radiation than a standard five-view radiographic examination (0.72 versus 0.96 mGy), and a 28-fold radiation reduction compared to CT (19.8 mGy).
  
  
  CONCLUSIONS
  Tomosynthesis delivers less radiation than a standard radiographic examination. For the wrist, it results in a 28-fold reduction in radiation compared to CT.
