The Christian ethical tradition introduces a number of key values into the clinical context. Moreover, although some denominational differences exist, these are essentially differences of emphasis rather than of substance. Among the central values which the Christian tradition promotes are: the dignity of the person, the individual as embodied spirit and the importance of the common good. Within the evolving discourse, social justice considerations have come to the fore as a critical concern within bioethics. In radiology, like most fields of clinical practice, practitioners frequently encounter conflicts and tensions of an ethical nature. Moreover, the manner in which these conflicts are articulated, conceptualised and ultimately resolved will depend, not only on how the scientific data are analysed and interpreted, but also on how different ethical frameworks are invoked in these disputes. The concern in this brief paper is to discuss the Christian ethical tradition as it is expressed in Roman Catholic and 'Protestant' denominations in the western church, considering the values and norms that underlie Christian ethical engagements with applied questions.
