[A report on experience with a second-generation PACS installation in routine computed tomographic operations].

PURPOSE

Our institute has been using a pilot SIENET-PACS system for the last five years; its advantages and disadvantages in daily use are described.

MATERIAL AND METHODS

The SIENET system connects 2 CT, 3 MRT and 2 angiographic installations with 7 viewing consoles and with an optical archive. From January 1994 to 1997 approximately 19,000 patients were examined by CT and the results stored digitally in the PACS system.

RESULTS

A representative analysis of selected patient data revealed problems in 12.8% of patients with regard to the radiological information system and also the hospital information system. While the digital data proved satisfactory, the production of digital images was excellent but time-consuming. The image archive was reliable but required greater capacity for our purposes.

CONCLUSIONS

Manual retrieval of patient data presented problems and integration of the radiology information system and PADS is essential. Digital data gathering is an advantage. Digital imaging is too slow and should be improved by more suitable software. Integration of new archival storage methods and compatibility with the DICOM standard is, judging form our experience, essential.
