Strain Measurement Activity

Please note this activity will require the use of strain analysis software.
We recommend that you use the latest version of Chrome or Firefox for the best experience.

From this learning activity you will:

  1. Have access to echocardiography images in patients receiving cancer therapy to measure global longitudinal strain (GLS).
  2. Be able to analyze the cases and send it back for expert review and feedback (personalized).
  3. Have the ability to compare your diagnosis of cardiotoxicity based on an external reference standard and clinical information.
  4. Use the personalized feedback to analyze a second set of cases to assess improvement in accuracy.
