Thank you all very much for the responses. Following some of @lassoan suggestions, we are using the [MONAIAuto3DSeg](https://discourse.slicer.org/t/new-extension-monai-auto3dseg-raise-the-bar-in-ai-medical-image-segmentation/35680) extension and the AI model: “Brain and intracranial hemorrhage (ICrH)” for segment the main areas of the brain (images attached). However, it does not segment as we expected (would like); the main lobes are what we would like.
