REPLY: All reasonable measures of course should be taken to minimize patient exposure without compromising the clinical value of any medical procedure. We know, however, that significant benefits are afforded to individual subjects who are exposed to radiation in the course of diagnostic medical procedures and that the associated risks are small, even if we accept the tenets of the linear-no-threshold model. Pat Zanzonico has now presented us with numeric estimates of the benefits of several medical studies. These data were presented at the 2007 ASNC meeting, and are currently posted at a Web site of the Health Physics Society (1). The complete analysis is to be published soon.
