The Effect of a PACS on Patient Radiation Doses and Operating Costs in a Radiology Department: A Practical Study☆

Abstract This study was conducted to investigate how the implementation of a picture archiving and communication system (PACS) affects patient radiation doses and operating costs of the radiology department. Doses were compared based on measurements of radiation loads before and after PACS operations. Obtained results showed that the use of PACS was significant in causing differences in the total radiation doses and in operating costs of radiology department.
