1. Why not segmenting the emboli? The scope of the challenge is accurate detection of the embolus, and not an accurate segmentation. In clinical practice it is important to locate where the emboli are, but not to quantify their size.
  2. I have this other annotated database of CTPA, can you include it into the challenge? We are open to include more data from different sources. Please contact the organizers to talk about the details and feasibility
