    This is very nice BUT need to fix one issue. When you have an ovarian lesion that has septations but NO solid component, the O-RADS algorithm for the next step is to make an assessment of whether the INNER wall and/or septations are smooth or irregular. As of right now (08/05/2023), your calculator does not include this step–instead, it incorrectly asks the user to assess the OUTER contour. Assessment of the OUTER contour is appropriate for a mass with solid components, but not for a cyst (with or without septations) that does not have a solid component. Fix this issue and the calculator will be accurate–but otherwise, nicely done.

    • Hello Dr. Patel,
      Thank you so much for bringing this error to my attention. I have made the necessary changes and now, if the lesion is completely cystic, the calculator will ask for “septations (if applicable) and internal contour” instead of the outer contour. I really appreciate your feedback.

    if we are using power doppler for ovarian lesion what is the color score to be followed ? If we use the routine color doppler scoring will it be an exaggeration of the score ?
