Cost/benefit of high technology in diagnostic radiology.
High technology is frequently blamed as a main cause for the last decade's disproportionate rise in health expenditure. Total costs for all large diagnostic and therapeutic appliances are typically less than 1% of annual expenditure on health care. CT, DSA, MRI, interventional radiology, ESWL, US, mammography, computers in radiology and PACS may save 10-80% of total cost for diagnosis and treatment of disease. Expenditure on high technology is in general vastly overestimated. Because of its medical utility, a slower deployment cannot be desirable.
