Evaluation of a sonographic PACS in clinical practice: analysis of technical and analytical time savings

The aim of this study was to generate quantitative data regarding technical and analytical time savings obtained by use of an ultrasonographic PACS. Data/time cards were recorded for each patient encountered in an outpatient diagnostic ultrasound facility for a 4 week period immediately before and a 1 year period after installation of a PACS environment. Use of a sonographic PACS resulted in a per case time savings of 293 s in the technical component and 51 to 63 s in the analytical component of an average ultrasonographic examination. We conclude that use of a PACS workstation has the potential to increase productivity for both the sonographer and the radiologist.
