PowerPoint is the standard software used for presentation at scientific meetings such as RSNA. Most presenters have become familiar with the basic function of PowerPoint, but few use the more advanced features such as add-ins. Add-ins are supplemental programs that extend the capabilities of PowerPoint by adding custom commands and specialized features. Add-ins can be written by the user using Visual Basic for Applications. Add-ins are also available from third parties. This exhibit discusses the use of add-in programs useful to the radiologist.
