Clinical application of low dose chest CT examination with PACS/RIS-HIS-Health screening system / 实用放射学杂志

ABSTRACT

Objective To investigate the clinical application of low dose chest CT examination with PACS/RIS-HIS-Health screening system.Methods 6038 subjects underwent chest low-dose CT examination were retrospectively analyzed in this study. With or without PACS/RIS-HIS-Health screening system,the physical examination workload per day,average examination duration and waiting duration were retrospectively calculated and compared,respectively.Results At the same working hours,the low dose chest CT screening workload was sharply increased from 73.87 to 127.4 per day (t=11.526,P<0.001).The mean CT examina-tion duration was decreased from 2.58 to 1.8 minutes per subject (t=8.443,P<0.001).30 percent of waiting duration were saved approximately (t=6.951,P<0.001).All the related management departments could do statistics and analyze the data online with high efficiency via the screening system.Conclusion PACS/RIS-HIS-Health screening system can optimize the workflow and im-prove the work efficiency of chest low-dose CT screening.
