Hello,

Could anyone recommend an extension to autocontour the prostate on either MRI or CT scan?

Thanks

Hi,

Following up on Sarah’s question, I wanted to highlight the current state of automatic prostate delineation/segmentation of the prostate in slicer3d.

So far as my knowledge goes, there is not any active extension that proposes this. However, publicly available AI-based prostate segmentation tools already exist outside of Slicer.

Potential AI-based pre-trained models candidates could be the official nnUNet-based prostate segmentation model, trained on PROMISE12 (Task024\_Promise), or newer models, also based on nnUNet framework, such as the [BAMF prostate segmentation tool](https://github.com/bamf-health/aimi-prostate-mr), or also MONAI-based ([prostate158](https://github.com/Project-MONAI/model-zoo/tree/dev/models/prostate_mri_anatomy)).  
These tools mentioned above were trained on T2W MRI images.

There is also an active effort to integrate dockerized AI-based pre-trained models inside of Slicer, such as the [SlicerMRunner](https://github.com/MHubAI/SlicerMRunner) extension, from the Medical Hub (mhub) initiative.
