Case editor: Create questions

Types of questions

You can create tree types of questions:

Creating and arranging questions

Questions are arranged in sequences and a case can have multiple sequence. A sequence can contain one or more question and you can control the order in which questions appear within each sequence.

  1. To create and arrange questions, make sure you are in the case editor, and locate the case editor menu.



     

  2. Click the                   icon to open the question menu and click 'add question sequence' to begin.
     

  3. In the question menu you can now add interpretation questions, preview your sequence, add your sequence to an assignment (once you have added questions), or delete your sequence altogether. If you add several questions to the same sequence, you can even change their order by drag and drop.

Create question: Interpretation question

Interpretation questions are standard multiple-choice questions with predefined answers, e.g. what is the diagnosis? or pathology in which region? To make it easier, we have already created the most common types of questions and answers, which you can choose from (dependent on your selection of medical specialty and sub-specialty when you imported the case to eScan Academy), but if something is missing please contract us at info@escanacademy.com so we can add it to our selection.

  1. Click 'add Interpretation' in the question menu, and you will see the following card.







     

  2. Select question and correct answer from the drop down lists.
     

  3. To manually select incorrect answers, click 'answer options'. Here you can specify the best alternatives, and use the arrows to change order of appearance. By default all available alternatives will be presented as incorrect answers.




     

  4. Click 'save'. Your question is now successfully added, and you can edit, preview, or add more questions in the 'question menu'.

 

Create question: Find region of interest

Find region of interest is an interactive and highly engaging component, where assignees must locate by (mouse)clicking on a predefined (but hidden) ROI or VOI in the image, e.g. locate pathology causing ileus in a abdominal CT. To create such question, you must first segment (draw) the desired ROI or VOI.

  1. Click the                   icon in the editor menu to open the segmentation menu. Click 'start drawing' to add an empty segmentation layer to your image.
     

  2. Before you can draw you must specify what you are about to draw by adding a label. Click 'add' (above the red text) in the segmentation menu to add a new label and select one or more labels from the list. Please contact us at info@escanacademy.com if a label is missing.
     

  3. Now you have access to a wide range of features to draw your ROI or VOI. We recommend you stick to the simple pencil tool by clicking on "draw segment", and adjust the brush size. You do not need to manually set the intensity. What will later (when you create the question) become the correct area must be clearly marked in blue.

















     

  4. Draw the ROI or VOI. Remember to draw in all relevant slices if you wish to create a volume.
     

  5. When you have completed your drawing, you are ready to convert it to a question. Go to the question menu and click 'add find region of interest', and your segmentation layer (drawing) gets automatically uploaded to eScan Academy. 
     

  6. Select your label from the list. By default, assignees have one attempt to locate and click on the ROI or VOI. Click on additional settings to change the number of attempts (tries), or to add a time limit to the question (sec).






 

Please note, if you change your drawing after you have converted it to a question you need to make sure your new segmentation layer gets uploaded to eScan Academy. You can click the upload button in the 'segmentation menu' or you can replace the existing question (with old drawing) with a new by repeating step 5 and 6, whereby your new segmentation gets uploaded automatically.

 

Create question: Describe region of interest

Describe region of interest is basically the opposite of find region of interest. A ROI or VOI is clearly presented to the assignees and their task is to describe the presented ROI or VOI by answering a series of multiple choice questions, e.g. what pathology is highlighted?

  1. Similarly to describe region of interest questions, you must first draw a ROI or VOI before you can create the question. Follow step 1 - 4 in the guide Create question: Find region of interest above.
     

  2. Once you have completed your drawing, you are ready to convert it to a question. Go to the question menu and click 'add describe region of interest', and your segmentation layer (drawing) is automatically uploaded to eScan Academy.
     

  3. Add your region of interest, and select correct and incorrect answers from the drop down lists.

Please note, if you change your drawing after you have converted it to a question you need to make sure your new segmentation layer gets uploaded to eScan Academy. You can click the upload button in the 'segmentation menu' or you can replace the existing question (with old drawing) with a new by repeating step 2 and 3, whereby your new segmentation gets uploaded automatically.
