title: [Pictocam instead of Pictogram - a quality improvement study in abdominal ultrasound imaging].
abstract: OBJECTIVE
  To replace pictograms with pictocam pictures: A prospective blinded quality improvement study in documenting image orientation and localisation in abdominal ultrasound imaging.
  
  
  METHODS
  A minicam was mounted on the ultrasound scanhead to record pictocam pictures. The primary examiner produced an ultrasound image together with the routinely embedded pictogram. Subsequently the pictogram was covered by the synchronically taken pictocam picture. Subsequently, the primary examiner assessed the pictograms and the second examiner the pictocam pictures (blinded to the pictogram findings of the primary examiner).
  
  
  RESULTS
  A total of 679 paired pictogram and pictocam pictures were available from 114 patients. The localisation of the utrasound head showed an absolute or close agreement of 99.7% (677/679) with a 95% confidence interval of [98.94%-99.96%]. The angle of the ultrasound head showed an absolute or close agreement of 99.0% (672/679) with a 95% confidence interval of [97.98% - 99.58%].
  
  
  CONCLUSIONS
  This study shows that the pictogram can validely be replaced by a pictocam picture. The routine addition of a minicam to the ultrasound scanhead would thus not only improve the quality of the documentation, but would also result in time savings during examinations.
