REVIEWS AND COMMENTARY:

Editorials:

Richard B. Gunderman and Indu Rekha Meesa: The Adoption of Innovation
If radiologists wish to maximize the rate of adoption of an innovation, they should attempt to ensure that it offers a substantial relative advantage and that it is relatively easy to integrate with existing technologies and practices, straightforward to learn and use, easy to try, and readily visible to those who might adopt it.

State of the Art:

Christiane K. Kuhl, Frank Träber, and Hans H. Schild: Whole-Body High-Field-Strength (3.0-T) MR Imaging in Clinical Practice • Part I. Technical Considerations and Clinical Applications
The higher signal-to-noise ratio at 3.0 T is clearly advantageous and the increased radiofrequency absorption in tissues at higher field strengths is disadvantageous—all other effects, however, can be both advantageous or disadvantageous, depending on the desired image contrast and/or the intended clinical application.
