DexNote is a reference resource for radiologists, spanning all of the major subspecialties. DexNote is designed for use in the reading room, enabling simple and intuitive, yet rapid and efficient, navigation of radiology information.

The complete database, available through in-app purchase, contains more than 30,000 entries, including more than 1,500 links to the literature and more than 500 images. The free trial database includes a small subset of this information to give the user an idea of how the full database functions.

DexNote displays information in three columns. Navigate to any particular item of interest by touching it. The relevant categories and subtopics are then shown in the leftward and rightward columns, respectively. The entire display may be shifted to the left or right by swiping. For example, with the item "hepatocellular carcinoma" selected as the item of interest, a number of relevant categories are listed. To browse these categories further, swipe the display to bring those items to the center. Back and forward history buttons are also available in the lower left corner.

The approximately 2000 web links and images are identified in italics. To display these items, simply touch and hold.

Please see the "About" tab in Settings for more information.
