A GOAL BASED COST-BENEFIT-ANALYSIS FOR FILM VERSUS FILMLESS RADIOLOGYDEPARTMENTS

We describe the use of spreadsheet models to compare differential cost s incurred in a film based versus a filmless radiology department. The spreadsheet allows a high degree of user customization to facilitate on-site cost analysis and informed purchasing decisions. Modeling inst itutions that perform 25, 50, and 105,000 diagnostic procedures per ye ar, we find that break-even occurs near 50,000 exams. Plots further sh ow the trends in annual hardware and staff costs as workloads increase . Copyright (C) 1996 by W.B. Saunders Company
