Using MONAILabel for vertebrae segmentation

Support
1

Hi,

I’m trying to perform inference using the pretrained model from the 3 stage vertebrae segmentation pipeline from MONAI Label, but have been running into a few issues on a Windows machine with Slicer version 5.2.1:

  1. I’ve been able to start the server and run the first step localization_spine without runtime errors, but unfortunately it produces empty segments. I’ve tried this using a nifti file from both Verse2019 and Verse2020, which are the datasets the 3 stage pipeline were originally trained on. I’ve tried other models such as the segmentation_spleen and the segmentation_full_ct from here:radiology_full_ct-upgraded-HYBRID - Google Drive, and those have produced mostly accurate output labels.

  2. I also tried running the entire vertebrae_pipeline, but this resulted in the following error:

Has anyone encountered similar issues? Thanks!

Hi. Yes. I couldn’t make it work either

Hi @DeepaKrishnaswamy,

Thanks for providing the details of your experience using MONAI Label here and on the issue here: vertebrae_pipeline produces an error during inference · Issue #1268 · Project-MONAI/MONAILabel · GitHub

It is good that you managed to run the vertebra model on the Medical Segmentation Decathlon dataset.

The vertebra segmentation model was trained only on a portion of the VerSe dataset (~60 volumes). I’ve also had similar issues with that dataset and I think it was because some files were corrupted or had wrong NIfTI headers.

If you have a GPU, you could also try the whole-body CT segmentation model available here: radiology_full_ct-upgraded-HYBRID - Google Drive

That model also segments all vertebras.

Thanks again!

Hi @mau_igna_06,

Is it the same error you faced last time?
As far as I remember the issue you faced was related to not having computing resources. Did you manage to run these models on a bigger GPU/CPU?
If you’re facing a different issue, please don’t hesitate to post the logs directly on the MONAI Label repository: Issues · Project-MONAI/MONAILabel · GitHub

Thanks!
