REVIEWS AND COMMENTARY:

Editorials:

David Gur: Imaging Technology and Practice Assessment Studies: Importance of the Baseline or Reference Performance Level
This editorial will address but one important issue related to inferences made as a result of pivotal studies that I believe has been largely ignored: namely, the performance level of the reference (often termed baseline or current) technology or practice.

Schild: Whole-Body High-Field-Strength (3.0-T) MR Imaging in Clinical Practice • Part II. Technical Considerations and Clinical Applications
To date, at the time of this writing, there has been relatively little published evidence available regarding the added clinical value of high-field-strength systems, and even regarding the seemingly simpler issue of image quality, 3.0-T systems may not always live up to user expectations.

Perspectives:

James H. Thrall: Globalization of Health Care
The globalization of radiologic professional services has not hurt U.S. radiologists economically and, to the extent that it has helped address onerous on-call work, has probably been a net plus for quality of work life and practice coverage issues.

Opinion:

David Gur, Andriy I. Bandos, and Howard E. Rockette: Comparing Areas under Receiver Operating Characteristic Curves: Potential Impact of the "Last" Experimentally Measured Operating Point
In the case of nonparametric analyses of differences in areas under the receiver operating characteristic curve (AUCs), the last experimentally ascertained operating point can significantly affect AUC estimates in a manner that could result in different study conclusions, as compared with AUC estimates derived when using the parametric approach.

Our retrospective reader study, which was designed to detect differences at least as large as those postulated for the primary Digital Mammographic Imaging Screening Trial (DMIST) study, did not show statistically significant differences between soft-copy digital and film mammography for Fischer, Fuji, and GE digital systems in either the full reader sets or in the subsets of women in whom digital mammography was found to be significantly superior to film mammography in the primary DMIST study.

With the underlying assumption that reported histologic biopsy specimens obtained at postoperative follow-up arthroscopy in prior studies have shown more fibrocartilage after microfracture therapy and more hyaline-like cartilage after matrix-associated autologous chondrocyte transplantation, our findings may suggest that quantitative T2 mapping can provide information about the structures of different cartilage repair tissues.

We have demonstrated that increases in relative cerebral blood volume (rCBV) precede the development of contrast enhancement by at least 12 months in transforming low-grade gliomas; rCBV increase is therefore likely to provide an earlier noninvasive indicator of malignant progression.
