Glenn S. Slavin and David A. Bluemke: Spatial and Temporal Resolution in Cardiovascular MR Imaging: Review and Recommendations
As multi–detector row CT and MR imaging may come to replace diagnostic angiography for certain applications, it is useful to review the principles of image resolution, to describe pitfalls in stating resolution, and to suggest standard means for researchers who report resolution that will ultimately aid journal authors, reviewers, and critical readers in comparing different imaging modalities.

Editorials:

Charles E. Willis and Thomas L. Slovis: The ALARA Concept in Pediatric CR and DR: Dose Reduction in Pediatric Radiographic Exams—a White Paper Conference Executive Summary
Most computed and digital radiography manufacturers recognize that pediatric patients are unique and have developed special provisions for pediatric exams, including image processing and accommodations for special exams like scoliosis.

Walter Huda: The Current Concept of Speed Should Not Be Used to Describe Digital Imaging Systems
Specifying the amount of radiation used to create a digital radiograph by using either exposure and/or air kerma is relatively straightforward, involves easy measurements, and avoids the ambiguities associated with the term speed.

Dieter R. Enzmann: A Different Look at Turf
Since radiologists have a tendency to overestimate the importance of technology, it behooves them to expand their understanding of how technology interacts with clinical practice models and why the practice model is the dominant factor in turf issues.
