In this study, overall technologist time was significantly shorter for the performance of tasks associated with direct radiography than for that of comparable tasks associated with computed radiography, a difference that appears to be the result of a number of factors, including but not limited to department-specific work flow, departmental layout, technology implementation, staffing, and system configuration.

With the combined-modulation technique, we successfully avoided an increase in radiation dose caused by the high attenuation of the metallic prosthesis in both the phantom and patients who underwent CT.

Richard B. Gunderman and William A. Engle: Ethics and the Limits of Neonatal Viability
A presumption in favor of life that leads parents and physicians to choose initial aggressive treatment for a potentially viable infant does not mean that a less aggressive strategy or change to palliative care may not be adopted at a later time.
