The torcular herophili, or "confluence of the sinuses," shows various configurations with other venous sinuses, as revealed by angiography. The aims of this study were to evaluate anatomic variations of this confluence and to assess their clinical relevance using three-dimensional (3D) computed tomographic (CT) venography. ⋯ Three-dimensional CT venography is useful as a noninvasive method to evaluate the confluence and its relevant dural sinuses and can provide useful information for surgical intervention.

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.
