Can you see bone cancer in the hips from a ct scan of the abdomen and pelvis?

Yes, some details se: Ct scan shows the normal anatomy of all the structures examined although it is not the best test for hip cancer which is best seen with a ct scan or MRI scan of the pelvis with a focus on the bones.

Likely: A ct scan of the pelvis should include the hip bones so one would likely pick up a bone cancer like ewing sarcoma, osteosarcoma or chondrosarcoma.
