NIBIB mobile app offers information about medical scans.

Understanding Medical Scans is a free app for mobile devices that offers helpful explanations of common medical imaging procedures. Developed by the National Institute of Biomedical Imaging and Bioengineering, the new tool’s goal is to explain to patients what to expect during a medical scan and how each type of scan can help with both diagnosis and treatment. 

Five types of medical scans are described in the app: positron emission tomography (PET), computerized tomography (CT), magnetic resonance imaging (MRI), ultrasound and x-ray imaging. The app uses question-based navigation, images and videos to highlight each of these state-of-the-art technologies. An additional topic within the app is the role of imaging in biomedical research. Developed with the layperson in mind, it may be helpful for patients and family members in formulating questions about pending procedures. 

The app can be downloaded onto an Apple or Android device, making medical imaging information easily available anywhere. Visit or search Understanding Medical Scans at the Apple store or on Google Play to download the app.
