[FEAT EXTRACTION] Will discontinuous ROIs work? #750

Closed amirzolal closed 2 years ago

amirzolal commented 2 years ago

Hello, this is rather a general question regarding the functioning of the algorithm. I have also posted this on slicer discourse but there was no reaction over several days.

I have some ROIs that I use to extract image pixel intensity from images and would like to re-use these ROIs in feature detection. However, the ROIs are discontinuous (meaning that the a specific tissue is marked on different places in the scan, without there being a connection between those tissues).

The radiomics program (at least pyradiomics) does produce a csv when using this ROI.

Will the output be anyhow affected by the discontinuity, i mean does the ROI border affect the feature recognition somehow?

Thanks in advance for the answer,

Amir

I'm not part of the pyradiomics team, but the case discussed here seems similar to yours:

@amirzolal, @giemmecci is correct.
