The high cost of new diagnostic and treatment technologies means that they have to be used selectively, and at that point decisions must be made about who should get to use them. In recent years there have been increasing charges of improper use of these new technologies, coupled with increasing discussion of their costs and benefits. Unfortunately, the use of such technology tends to spread indiscriminately and so add indiscriminately to health care costs. Given this situation, there is a need to examine the relevance of new diagnostic and treatment methods, the causes of technological abuse, the ethical aspects of the use of medical technology, and even the relationship between technology and society. Indeed, if there is to be generally effective acquisition and use of health care resources, such examination is essential.
