Hi Nick, excellent work with KiTS21 :)

I noticed that Instance 1 Cyst and Instance 3 Tumor refer to the same structure in case 00205, is that intended?. Considering that there was no Tumor region in KiTS19 I guess it is supposed to be a cyst.

Best, Michael

That was not intended, and thank you for catching that! My feeling is you are correct but let me consult with our clinical team and get back to you.

In fact, this was a label error from KiTS19, and it is correct as a tumor. This is an angiomyolipoma case and that can cause tumors of very low radiodensity. It was originally erroneously labeled as a cyst but was later reclassified as a tumor. Unfortunately, due to a bug in our import script, the original cyst instance was not deleted, and that is why it appears twice.

I've merged in a change which deletes these instances. Thanks again for the heads up!
