Dianna D. Cody, Donna M. Stevens, and Lawrence E. Ginsberg: Multi–Detector Row CT Artifacts That Mimic Disease
Because of the risk of misinterpreting artifact patterns as pathologic lesions when multi–detector row CT scanners are used in the axial mode, we recommend that radiologists, technologists, and physicists be aware of these possible artifacts and that they implement rigorous quality assurance programs to detect and correctly identify anomalies.

Compared with radiography alone, MR imaging in patients with acute wrist or ankle injury is neither cost saving nor more effective in expediting the work-up or improving quality of life, but, in patients with acute knee injury, MR imaging shortens the diagnostic work-up, reduces the number of diagnostic procedures during follow-up, improves quality of life in the first 6 weeks, and, although not statistically significant, may reduce costs associated with lost productivity.

Thomas Schlosser, Peter Hunold, Christoph U. Herborn, Heidrun Lehmkuhl, Alexander Lind, Sandra Massing, and Jörg Barkhausen: Myocardial Infarct: Depiction with Contrast-enhanced MR Imaging—Comparison of Gadopentetate and Gadobenate
At 15 minutes after contrast agent injection, a comparison of the contrast-to-noise ratio (CNR) values of the infarcted myocardium with those of the normal myocardium showed that the CNR values were significantly higher on the gadobenate-enhanced images than they were on the gadopentetate-enhanced images; however, myocardial infarcts were better delineated on the gadopentetate-enhanced images than they were on the gadobenate-enhanced images because of improved contrast between the infarcted myocardium and the left ventricular cavity.

When compared with the more conventional Cartesian k-space sampling approach, radial data acquisition minimizes motion artifacts and therefore leads to further improved image quality and vessel visualization.

Henrik Watz, Andreas Breithecker, Wigbert Stephan Rau, and Andres Kriete: Micro-CT of the Human Lung: Imaging of Alveoli and Virtual Endoscopy of an Alveolar Duct in a Normal Lung and in a Lung with Centrilobular Emphysema—Initial Observations
By combining pressure-controlled inflation of the lungs with hot formalin vapor and subsequent staining of lung specimens with silver nitrate in a vacuum, we were able to establish the preparative requirements for use of micro-CT in the investigation of human lung parenchyma and assess the potential of this technique for imaging of alveoli.

Dean D. T. Maglinte: Capsule Imaging and the Role of Radiology in the Investigation of Diseases of the Small Bowel
As more experience with wireless capsule endoscopy and the recently introduced patency capsule is reported, the role of radiologic investigations in the elective clinical investigation of diseases of the small bowel will need to undergo reevaluation.
