Dear members,
I've been working on delimiting the pericardial surface of the Heart and I've finally been able to do that semi-automatically using a EATSeg tool available on GitHub. This tool creates a ROI encompassing the entire pericardium (+heart inside). I then exported the ROI to 3D Sclicer and merged it with the DICOM file, creating the imagem that I attach bellow.
However, I am only interested in the pericardial fat, so, what I was wondering was if there was any way to create a ROI within the pericardial ROI containing all the volume of tissue corresponding to adipose tissue (ie, with HU between -150 and -50).
Hopefully someone has dealt with this issue before and could help out
Thank you
Fábio Nunes
Dear Fábio Sousa Nunes ,
I apologize if I didn't understand your question however, I suggest the two following procedures:
Hope this helps.
Best wishes.
Thank you for your input.
I've actually solved the question by exporting the entire DICOM file + mask to pyradiomics and then I've chosen the HU of interest.
In another forum, someone suggested another solution that also works. Here it is, if you have the same problem (I've done it over at 3D Slicer)
"You can achieve this with Threshold effect with masking.
- Create a new segment
- Select Trheshold effect
- Set the desired range
- In masking section (near the bottom) choose editable area → inside all segments
- Click Apply
These can be automated easily, by writing a few lines of Python script."
