[Effectiveness and cost effectiveness of innovative medical techniques in public health].

Electromedical technology and systems are an integral part of health services and contribute to their costs. Despite the sometimes high capital costs, they have proved to be effective and efficient for health services. Technological assessment with respect to benefit and cost aspects has been well and systematically evaluated, but requires much work in detail. In many cases less sophisticated procedures are sufficiently effective for a reliable evaluation. Corresponding results that show the cost-saving potential of advanced technology for radiology are reported.
