Hello everyone,

I am trying to segment multiple structures in an abdominal ct. There are 5 structures that I would like marked individually: Psoas muscle, Other skeletal muscle, Subcutaeous fat, intramuscular fat and visceral fat.

I’m fairly new to the app and I’m having a hard time figuring out the fastest and most efficient way to do it.

any suggestions? is there an established extension that can do it?

Thanks

You can segment muscles on CT using TotalSegmentator or MONAIAuto3DSeg extension. You can combine the segments with thresholding to obtain intramuscular fat.
