And surprisingly, no one realized that Adobe Photoshop is one solution, even though all these users already have the software installed on their computers (i.e., departmental site license). Some realize the advantage of using animated GIFs over movie clips but do not know how to convert the files. Most users report that animated GIF is not available on their workstations, only movie clips. A survey in our department (94 radiology users: 52 faculty, 32 residents, and 10 fellows) yielded the following interesting results. Unfortunately, many academic radiologists still struggle with the issue of incompatible codecs and missing file links when showing movie clips in PowerPoint. Given these two merits, animated GIF is a more appropriate choice.

Second, movie clips must be linked externally to PowerPoint, but an animated GIF is embedded as part of the presentation file, similar to other images such as JPEG and BMP. First, movie clips are usually created using special software algorithms called codecs (COmpressor and DECompressor) an animated GIF does not require a codec. Although the basic purpose is the same-that is, displaying data set images as a movie loop, these two types of file formats are rather different in file structure and PowerPoint compatibility.

Animated GIF (graphics interchange format) and movie clips (e.g., AVI, QuickTime, and MPEG [Motion Picture Experts' Group) are the two most popular file formats used by radiologists for presenting dynamic data sets (movie loops of images) in Microsoft PowerPoint.
