Are the ground truth masks really correct?

Dear Organizers,

There are couple of cases like the following one in the training data, which I assume would be over-segmented (I am not a radiologist but from an observer-eye). I wanted to share this to see, whether the highlighted part in blue are really part of the kidney or not?

Regards

Thanks for the question! It looks like the feature you’re referring to is a renal cyst. These were intentionally included in our “kidney” label.
