4.2 Image Gently Universal Protocols

The Image Gently campaign and website were conceived by the Alliance for Radiation Safety in Pediatric Imaging in 2007. The Image Gently website (www.imagegently.org) contains a multitude of resources, including explicit guidelines for developing age and girth-based pediatric CT protocols (Fig. 11) (The Alliance for Radiation Safety in Pediatric Imaging 2008; Strauss 2008). The Image Gently pediatric protocols key off of the site’s adult CT doses. This produces the relative level of quantum mottle in the pediatric images that are relatively independent of patient size and based on the basic level of quantum mottle that the radiologists have selected for their adult patients.

Fig. 11This table lists a simple method to lower dose for pediatric patients using the Image Gently “universal protocols” available on the Image Gently website. This table assumes that the site is accredited and that the adult protocols fall within the ACR guidelines. Hospitals may use these protocols to work with their medical imaging physicist to lower dose further for pediatric patients as needed.
