title: [Dose reduction in abdominal computed tomography].
abstract: OBJECTIVE
  The broad availability and use of multidetector computed tomography (MDCT) in recent years has increased the radiation dose for patients.
  
  
  METHODS
  Multiphase MDCT protocols are used in abdominal imaging for various indications.
  
  
  METHODS
  Dose reduction though novel technologies, such as dual energy CT or adapted contrast injection protocols (split bolus etc.) for reduction of scans.
  
  
  CONCLUSIONS
  An optimized dose reduction can be achieved by using strict protocols which are adapted to the clinical situation of the patient.
