Dean D. T. Maglinte: Science to Practice: Do Mural Attenuation and Thickness at Contrast-enhanced CT Enterography Correlate with Endoscopic and Histologic Findings of Inflammation in Crohn Disease?
Bodily et al in this issue of Radiology have described an objective, more reliable, and hopefully reproducible method of measuring active inflammation of a segment of bowel by quantifying mural enhancement in patients examined with CT enterography.

REVIEWS AND COMMENTARY:

Editorials:

David Gur: Lung Cancer Screening: Radiology's Opportunity Here and Now
When considering screening for early detection of lung cancer, we should be able to learn from the processes undertaken in breast cancer screening and not have to repeat at least some of these steps before exhibiting strong support toward the initiation of such a program—at a minimum as a large field trial in a high-risk population.

Jerome M. Reich: Assessing the Efficacy of Lung Cancer Screening
Swensen et al reported no significant difference (P = .43, Poisson regression) in incidence lung cancer mortality (2.8 vs 2.0 deaths per 1000 person-years) among men screened with low-dose CT who were matched for age and duration of follow-up with men who underwent conventional radiographic screening in the earlier Mayo Lung Program.

Gustav K. von Schulthess, Hans C. Steinert, and Thomas F. Hany: Integrated PET/CT: Current Applications and Future Directions
All currently available data indicate that combined PET/CT is more sensitive and specific than either of its constituent imaging methods alone and probably more so than images obtained from separate PET and CT systems and viewed side by side.
