Thanks for the follow-up @joshuacwnewton ! We are in the process of finalizing the contrast-agnostic model this week. Once it's done, I will post the QC report of the model tested on some subjects with compression! Thanks for your patience!
Hey @joshuacwnewton ! It's been a while but we have gotten around to this finally! The latest release of contrast-agnostic
(which is also in SCT v6.3 now) works reasonably well on compression data. Please let me know if there are any subjects you wanted to test.

Personally, I'm not sure which subjects to test on outside of the image mentioned in the original issue:
path to image : /duke/projects/ml_sci_prognosis/issue/issuedeepseg#2470
Thankfully, the image is still at the same location, so I tried running the contrast agnostic model, and the results are significantly better (no empty slices, much more accurate segmentation):
(Red: sct_deepseg -task seg_sc_contrast_agnostic
, blue: sct_deepseg_sc
)
We can test on more subjects, of course, but I think in the context of the original SCT issue, the problem with sct_deepseg_sc
has been fixed. :)
amazing, thanks for the quick testing!
I think we can close this issue? (Unless we want to come up with some sort of benchmark testing dataset for comparing different SC seg methods... but that seems like a paper in and of itself, hehe.)
some sort of benchmark testing dataset for comparing different SC seg methods
This is actually a great idea! Right now, we're just using randomly using those datasets which happen to come to mind during our project meetings. But this is not ideal as datasets evolve and new datasets are added. Maybe having a (hopefully, public) dataset could be useful.
Moreover, in a lot of ML/DL papers, testing against some benchmark also makes it easy for the reader to objectively judge the performance of the method/model.
I added it to the agenda for the next SCT meeting. But, as for this issue, it can be closed now I believe !

Received a comment saying:
This issue is for following up on the task of verifying whether the new model performs better than the existing models on images with spinal cord compression.
