Symmetry is a useful tool when reading radiographs; if you happen to have both hips, for example, experienced readers will immediately compare and contrast the two sides.
Look at this image, and compare the femoral caps. Note that the right has a smaller volume, is flattened, and (with the eye of faith) you can see it as more sclerotic. This is an example of avascular necrosis of the femoral head. What conditions predispose to this? What is Legg Calves Perthes disease?
