There has been a great deal of discussion as to the cost and benefit of introducing filmiess CRT diagnosis for radiological exams. Although the various advantages of the filmiess system tend to be highlighted, very few studies have attempted to provide a quantitative estimate of the degree of impact. We analyzed the potential financial impact on the cost of film management (film development, maintenance, and transportation) if CRT diagnosis were to be introduced in Seirei Hamamatsu Hospital. In conducting this analysis, we assumed that CRT diagnosis initially would be limited to CT and MR. The analysis demonstrated that the actual yearly cost of managing films amounts to about 240 million yen. As individual items, the cost of film materials, labor, and depreciation of assets were the three largest cost sectors, with the cost of film accounting for more than 30% of the total. The expense attributable to CT and MR exams was roughly half of the total cost. Against this level of expense, the expected savings in the first year after shifting to the filmless system would be 100 million yen, or a 36% reduction in current expenses. This savings reflects various effects of system change, including lack of need for related materials, reduction in staff workload, elimination of unnecessary equipment, etc. Under the simulation we conducted, 70% of savings occurred in the area of variable costs and 30% in the area of fixed costs.
