Use of a low-cost, PC-based image review workstation at a radiology department.

Despite the increasing use of diagnostic workstations, film reading is still commonplace in most radiology departments all over the world. The purpose of this work is to assess the adoption of image review workstations in a radiology department where the usual primary diagnosis is film-based and cannot be replaced with diagnostic workstations. At our institution, a tertiary care center specialized in diagnostic imaging, a pair of PC-based review workstations running a Digital Imaging and Communications in Medicine (DICOM)-conformant public domain software for image display and analysis were installed in two reading rooms. Studies are automatically routed after acquisition from the picture archiving and communication system (PACS) server to the workstations and remain available for visualization for approximately 15 to 20 days. Data from two radiologists and two technologists collected over a 3-month period were analyzed, including purpose of use, time savings as compared to traditional manual methods, and overall user satisfaction. The results from the analysis presented in this work indicate a high degree of approval from the users, who report significant timesavings in numerous circumstances, in particular when it comes to discussing findings with referring physicians whenever films are not available. It also enriches communication between radiologists, facilitating peer review on the telephone when one of them has questions at the outcome of any given study. One of the main advantages associated with the system is the possibility of using it as a powerful tool for teaching and research. In conclusion, even when primary diagnosis is performed on film, the availability of a PACS for review can be helpful to enhance communication with referring physicians, as well as technologists and radiologists' efficiency. Our experience shows that it is possible to implement such a system using low-cost or freely available components without compromising ease of use while keeping costs down, which is a major concern in developing countries.
