I’m new on Slicer !I’ running a project and i need some software to correct flow artifacts on T1 after gd injection ,intencity correction due to distance from isocenter ,and maybe BBB leakage correction!?I think correction is needed before starting any segmentation process and exporting models!Thank you!

Hi @thanos - I don’t think we have anything for BBB leakage, but you might want to look at using the [N4 bias correction module](https://www.slicer.org/wiki/Documentation/4.10/Modules/N4ITKBiasFieldCorrection).
