Totalsegmentator_mri fails for non-whole-body-MRI and contrast enhancement

[Nanex101195]

I have abdominal T1-VIBE sequences and totalsegmentator always predicts some lung, where never has been any lung visible. Also segmentation of other organs is not really competitive. I tried it with native T1, as well as contrast enhanced T1s. With contrast enhancement of the liver for example, the model fails completely to predict anything.

How can you claim a "sequence independentness" in your arxiv preprint, where segmentation on MRI is not even scanner invariant in most cases?

For CT this might hold up with the absolute HU, but for MRI? In my tests, it didn't work as explained in your paper, to be honest. I think the inhomogeneities of each MRI Scanner, let alone the sequence specific intensity distributions are not really possible to overcome. Can you explain to me, how you were satisfied with the "sequence independent" claim? I can't understand this in any way and want to understand your thought process about this.
