Images tab: Images and DICOM studies are added to the case on the Images tab.

Uploading images: Images can be uploaded in one of two ways:

Annotated images: In the TF presenter, the non-annotated images and the annotated images are linked together. In order to upload an annotated image, click/select the uploaded non-annotated image of the annotated image you wish to upload. The non-annotated image will appear with a blue border. This is the image that will be linked to the annotated image. Drag and drop your annotated image to the “Drop files here” next to the Annotated images label or use the “Upload Files” button. Once a non-annotated image has been linked with an annotated image, the user will see that both images will have blue borders around them, letting you know they are linked. To annotate an image using TF Edit, refer to Image Annotation using Teaching File (TF) Editor.

Deleting Images in TF Editor: To delete an annotated image, select the image and click the Delete button under the annotated image in the "Annotated Images" box. If you delete a non-annotated image and it has an associated annotated image, the annotated image will also be deleted. Refer to Deleting Images and Annotated Images in Teaching File (TF) Editor for additional information.

Note:An image may not be deleted if it is referenced within the case as a hyperlink. Use the box below the images to add a caption. Check the “Show Caption” check box to allow the user to view the caption during presentation.

Previewing a case: Click on the Preview Case link in the upper right corner to view the case in the TF Presenter. This will open a new tab in your browser (or a new window depending on your user settings) where you will be able to preview your case in the web browser.

Create Case: A drop down selection that allows the user to start a new case.

Advanced Edit: Depending upon your account privileges, the Advanced Edit link may or may not be displayed. This link takes the user to Cortex advanced area.

Finish Editing: The Finish Editing button exits the edit mode and locks the case.

Things to Know:
Although the case editors are flexible and allow users to edit all cases using any editor type, there are some limitations on what can be done due to editor functionality or case content.

Limitations: Subspecialty is a mandatory field which is not required for some case types such as RADS.

  1. The case script is not available and cannot be edited using TF Edit. Users can still add/update text items, images and questions and these updates can be viewed while presenting the case (even if the item is already in script).
  2. TF Edit does not support NLP and Detection type of questions.
  3. Some presenters only support limited text items so although multiple items may be entered for the case, they may not be displayed.  TF Presenter only displays the first text item for each text category.
  4. TF Edit does not support the Definition, Comments or Physician chat items required by RADS cases.


  1. For script based cases such as Case in Point, use the New Case Wizard (Case Script Editor).
  2. For RADS cases, use the RADSEdit interface.
  3. For WIDI cases, use the WIDI Edit interface.
