Operating system: Windows 10 Slicer version: 4.10.2 Hi, how to do a mammographic density segmentation in order to show automatic identification of breast density? Thank you, Paola

You can segment the ROI(the white area and green area in your picture) and then get the each area statistic in segment statistic module. [image]

Slicer has many tools for this kind of analysis. If you can write a bit more about what you would like to achieve (or provide reference to a paper that describes a workflow that is similar to what you would like to implement) then we can give more specific advice.

I would like to achieve an automated brest density assessement. In the work I mention below the software automatically identified on the mammogram the pixel with higher intensities. The density was measured in percentage. It’s what I am willing to reproduce. Thank you DOI 10.25259/JCIS_70_2019 […

[image] New module for measuring user statistics Support Thanks for the feedback. I’ve added a button to the user information popup to disable User statistics by a single button click (and tables are not created anymore if the feature is disabled). I’ve added a bug report …

Thank you. I am wondering if there is a way to segment automatically the ROI and to let the software calculate the pixel with higher density within that ROI.

If simple thresholding can segment the high-density area then the process can be made fully automatic very easily by writing a short Python script. See examples here: https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#How_to_run_segment_editor_effects_from_a_script You may find “cre…

By thresholding the segmentation seems suboptimal. In the picture I posted the author could “colour” just the fibroglandular breast parenchyma. Thank you

The screenshot in the image indicates that the authors used “Level tracing” effect in Editor module (which correspongs to “Segment Editor” module in current Slicer version).

I had the same intuition but selecting “Level tracing”, the program don’t let me do any operation on the DICOM file. I thought there was the need of doing something else before but can’t find it. Thank you

Once you have your segment highlighting the region of interest, you can follow the steps described above to get the density. Would you expect to do any other operation on the DICOM file?

Hi, i want to know how to make dense tissue segmentation from tomosynthesis images? thank you
