The authors outline the steps involved in setting up, maintaining, and evaluating an evidence-based imaging journal club, using their collective experience at the University of Michigan. The article opens with a background to journal clubs in general and describes their changing purpose or role in recent decades. This should act as a useful framework or "how-to" guide to get things started. ⋯ In addition, useful information, references and links to useful resources are also given throughout the article. Finally, the authors share the positive (and negative) experiences of setting up, maintaining, and evaluating the University of Michigan's journal club, now in its third year. The authors welcome feedback from readers who have been involved in evidence-based imaging journal clubs to share their experiences, good and bad.

The h index is a recently developed tool to assess the impact of an author's publications. The purpose of this study was to apply and evaluate the h indexes of US academic radiologists. ⋯ There exists a significant relationship between h index and academic rank, with h index increasing with academic rank. These results offer a benchmark for comparing a given academic radiologist to national averages.

The aim of this study was to assess the findings of chest radiography and high-resolution computed tomography in patients requiring intensive care unit treatment for severe H1N1 virus pneumonia. ⋯ Patients requiring treatment in an intensive care unit for severe H1N1 pneumonia are at high risk for developing acute respiratory distress syndrome and frequently require ECMO therapy.

The aim of this study was to examine the geographic origin of publications in the highest impacting radiology journals and to examine the link between the percentage of gross domestic product (GDP) spent on research by a country and the output of radiology publications. ⋯ The United States is the most productive country in absolute number of publications. The flaws of using population size to compare publication output are clear, and a comparison using GDP and the percentage of GDP spent on research may give more meaningful results. When GDP is taken into consideration, smaller European countries are more productive. The importance of investment in radiologic research is emphasized by the association between increased funding of research and the number of publications in high-impacting radiology journals.

Lung resection for primary bronchogenic carcinoma in the setting of chronic obstructive pulmonary disease often requires a detailed assessment of lung function to avoid perioperative complications and long-term disability. The aim of this study was to test the hypothesis that a novel technique of spiral computed tomographic (CT) subtraction imaging provides accuracy equal to the current standard of radioisotope perfusion scintigraphy in predicting postoperative lung function. ⋯ A novel technique of CT subtraction imaging is equally accurate at predicting postoperative lung function as radioisotope perfusion scintigraphy, which may obviate the need for additional nuclear imaging in the context of the preoperative assessment of resectable lung cancer in high-risk patients.
