It's not about the size as much it is about the content...CT can better delineate structures that show a contrast to the surroundings that can be hyper or hypo to the surroundings... Also it depends on the resolution of the scans which in turn depends on various factors like slices ? Pitch etc... Correct me if I am wrong..
