Body composition - abdominal muscle segmentation with total segmentator

Heya, I’m currently using total segmentator subtask - tissue 4 type for abdominal muscle segmentation, however I noticed it doesn’t pick up transverse abdominis at all and is not the best at segmentating iliacus. I’ve just been manually painting the TA layer which takes ages, any good suggestions on how to approach this? does everyone else also have the same issue? (But otherwise this is a perfect segmentation subtask!)

You might have better luck with the original model. If you noticed different results please report back. It’s not directly integrated with Slicer but it shouldn’t be hard to install and use.
